Chocolate and peanut
Not a nut, and the most successful chocolate pairing in commercial history. Roasted peanut is intensely savoury and salty-adjacent, which is doing something no other nut does at the same strength.
Peanuts are legumes, and their amino acid profile browns differently from a true nut's — roasting produces a heavier, more savoury, more umami-adjacent aroma with pronounced pyrazine character. That is the same compound family roasting produces in cacao, which is why roasted peanut and chocolate feel like one flavour rather than two.
The other half of the pairing's success is salt. Peanut products are almost always salted, and salt suppresses bitterness perception while raising perceived sweetness — so a salted peanut alongside chocolate is doing the same work a pinch of salt does inside it, at a much larger dose.
That combination of shared roast character and built-in salt is why peanut and chocolate has produced more successful confectionery than any other pairing on this site.
The principle
Roast character plus salt. It works with everything from unsweetened to white, and the variable is how much sweetness the chocolate is contributing.
Pairings
Milk chocolate's dairy and caramel notes sit directly under roasted peanut's savoury weight, and neither is fighting for the same register.
For example: salted peanut in milk chocolate; peanut butter cups
The salt in a salted peanut suppresses dark chocolate's bitterness directly, which makes a high-percentage bar noticeably more approachable alongside it.
For example: salted peanuts with a 70% bar
Unsalted peanuts do not do this. The pairing loses most of its power without the salt, which is worth knowing before buying the expensive unsalted ones for it.
Peanut and cacao are combined in several West African and South American preparations, and a spoonful of peanut paste in a drinking chocolate is a direct and very good route to it.
For example: a teaspoon of unsweetened peanut paste whisked into hot chocolate
Commonly recommended, and frequently disappointing
Peanut with white chocolate is much harder than it looks. White chocolate has no cocoa solids and therefore no bitterness, so there is nothing to balance the peanut's savoury weight and the result is flatly sweet unless salt is added deliberately.
Serving
If you are pairing rather than eating a confection, roast the peanuts yourself and salt them warm. Commercial roasted peanuts have generally been sitting in oil-permeable packaging, and peanut oil goes rancid faster than most.
