What Are Chocolate Inclusions? (Guide to Flavored Chocolates)

Sharing is caring!

Think of your favorite chocolate; just humor me. Is it a smooth milk chocolate? Or a dark bar with whole almonds on the back? Oh, or maybe a sweet white chocolate with bits of dried fruit? Whatever your fare of choice is, I’m sure you’ve run into some variants of those chocolate flavors.

The last two chocolates I mentioned actually feature inclusions, an industry term for any substance added to chocolate beyond the widely accepted ingredients (cacao, cocoa butter, sugar, milk powder, vanilla, and lecithin). In this article we’ll dig into what constitutes an inclusion and what types of inclusions are out there, from coffee & cacao nibs to passion fruit pulp. Should you be using inclusions in your chocolate recipes?

This article was first published in 2015, and updated in 2021 to reflect the major growth and changes in the industry in the years since. To read about the evolution of nondairy milks in chocolate, click here.

What are Inclusions in Chocolate?

Inclusions are extra ingredients added to chocolate, intended to improve the chocolate’s overall impact, either flavor-wise or aesthetically.

Sometimes a chocolate maker or chocolatier adds inclusions for both flavor and visual appeal, much more common these days considering that we “eat with our eyes.” One of the most common inclusions is vanilla. However, vanilla is so ubiquitous that it has become somewhat neutral territory in chocolate, and therefore is not generally considered a part of the “inclusion” category. In fact, to be considered as a contender in the Good Food Awards‘ Chocolate “Inclusion” category, a bar must include a flavoring ingredient other than vanilla!

General categories for inclusions, with examples:

  • Fruits (sun-dried cranberries, freeze-dried strawberries, apple bits)
  • Extracts (spearmint flavoring, bitter orange extract, ginger oil)
  • Herbs & Spices (peppermint leaves, ground cardamom, whole peppercorns)
  • Salt (sea salt, flake salt, salt crystals)
  • Nuts & Nibs (roasted or raw cacao nibs, whole nuts, praliné)
  • Miscellaneous (olive oil, caramel, rose petals)

You may think it’s obvious how these ingredients affect the chocolate’s final flavor— they make the chocolate taste like the inclusions, right? But this isn’t always the case. Any chocolate reviewer can humbly impart this truth. Each ingredient, down to the added cocoa butter, affects the final experience for the consumer. The state of the ingredient, and when & where they’re added during the chocolate making process also affect flavor & texture.

Jose Meza, Co-founder of Mindo Chocolate in Ecuador, has actually had a very unique approach to inclusions. When I interviewed him in Ecuador back in 2015, he was experimenting with adding inclusions directly to fermenting cacao. In one batch of beans I tried, he had added guava to the fermenting trough, imparting guava flavor to the beans without adding guava to the final product. Many believe that similar such projects may have been the inspiration behind Ruby Chocolate.

Inclusion Categories, In-Depth

Fruits

Bar example: Ginger Milk Chocolate by Alluvia

Fruits of any kind are almost always added at the end of processing, to the back of a freshly-tempered chocolate bar. Sometimes, however, they’re added during cacao’s fermentation (see above) or mixed in at the end in the form of a puree (similar to Zotter Chocolate’s hand-scooped bars). They tend to add a less-strong flavor than extracts, and a pointedly chewy or crunchy texture. Sometimes a dash of salt or a sprinkle of nibs are added to emphasize the fruity sweetness, but in general, fruit clashes with other inclusions.

Extracts

Bar example: Rose Lychee Nibs by Fuwan Chocolate

Always blended throughout the chocolate, extracts are added at the end of processing due to their fragility. Natural extracts such as ginger oil have the tendency to lose their flavor potency if heated, as would happen several times during the refining stage of the chocolate making process. Note that most bars will not include more than one flavor extract, due to their tendency to overwhelm the palate in high quantities.

Herbs & Spices

Bar example: Strawberry Basil by Raaka

Treated similarly by makers in terms of when and where they are added, herbs and spices are more popular with chocolatiers than with chocolate makers. Like extracts, herbs & spices such as peppermint leaves tend to lose their potency if exposed to too much heat, so they’re always added at the end. Most of the time they’re sprinkled delicately onto the back of the bar, just enough to stick onto the chocolate, but not so much that they’re all you can taste. Only the most finely-ground herbs and spices are blended into the chocolate, and this is also done at the end of the process.

Salt

Bar example: Sea Salt 70% by French Broad

It seems like a straight-forward addition to any well-meaning chocolate bar, but this is likely the most common chocolate inclusion, as well as the most flexible. Though chemically the same, each type of salt behaves differently in the presence of chocolate, depending on crystal size, source, when it was added, and paired inclusions. The most common form is large sea salt crystals— possibly because it sounds fancier— added to the back of a bar.

The sea, to be fair, is one of the most pure and aesthetically striking sources of salt available. If it is mixed into the bar, it can get so lost as to seem like a flavor note, and this is not an uncommon occurrence. That is why craft chocolate bars usually feature big crystals added to the back of a bar by hand. In this way, the taster can experience the pointed contrast between the sweet bar and the salt, each enhancing and complementing the other for a longer period.

Nuts & Nibs

Bar example: The Breakfast Bar by Manoa

They come from similar places, both finding their origin hanging off of a branch, but they’re vastly different in final effect. Nuts add a crunchiness (or a chewiness if they’re old), and they tend to taste sweeter and earthier when raw. For example, macadamias add a sweet creaminess and nibs a brownie-like crunch, while peanuts lend a Reese’s vibe. But cacao nibs are usually from the same origin as the cacao used to make the chocolate, so they have a reputation for emphasizing the sweetness in a bar by being not-sweet & often bitter.

These inclusions are pretty powerful flavors, so like extracts, they used to be added to lower-quality chocolate. Thankfully this is changing, as makers play around with the ingredients in their single-origin bars. But beware of imitators. Even craft chocolate with inclusions should still mention an origin for their beans, and not use any preservatives or strange-sounding chemicals. Nuts and/or nibs are usually paired with salt, if combined with any other inclusions.

Miscellaneous

Bar example: HSU Special Edition Bar by Dick Taylor

This is the catch-all category, and as such it’s hard to make generalizations about these inclusions. However, unlike more traditional inclusions, these are usually more expensive & harder-to-find or local ingredients. Fruits, nuts, spices; all of these can be found in varying quantities in all corners of the world, and it makes sense that makers might want to showcase them. Thus, bars which include an off-the-wall ingredient are usually a limited edition bar or a chocofied version of a local dish.

Some examples are rose petals on Ecuadorian bars, dulce de leche swirls in Argentinian chocolate, and olive oil & rosemary truffles in Italy, each of which adds textural depth as well as a contrast to the chocolate. Not all of these are craft chocolate, but they certainly could be. The quality of base chocolate used with such inclusions varies by maker, but if you like their single-origin bars, I’d take the leap and try one of their local specialties.

Why are Inclusions Significant to Experience?

At first glance, the point of inclusions seems to be familiarity, making the chocolate taste like something less rich, or more recognizable. But this ignores the fact that many makers add one flavor in order to emphasize another. In commercial ventures, often inclusions are meant to complement or cover the inherent flavors of cacao beans. They trick your palate by using both your nose & eyes to steer your brain in one direction or another.

By creating expectations through both sight and smell, added flavorings potentially do no more than help you realize what flavors were already there. Salt is usually used to make a bar taste sweeter, and fruit to bring out bright citrus or berry notes already present in the bar. Nibs are added to emphasize the flavor value of processing them into chocolate; no new ingredients are added, yet the same cacao can taste like a whole different food group.

My words are not the be-all, end-all on inclusions— there are exceptions to every rule. However this should serve as a guide to chocolate inclusions for all those curious about how their taste buds and nose are affecting their level of contentment (both with their new favorites and the old stand-bys).

If you’re a chocolate maker, one way to appeal to a wider audience is to experiment with inclusions in bars. Adding inclusions to chocolate is a simple way to widen your customer base, especially when people see unique creations that they’d love to gift. Again, the eyes are the window to the soul AND the stomach. So why not add in some interesting inclusions the next time you’re looking for a breath of fresh air?
