Nut confections, and the allergen line they draw

The craft transfers directly

Brittle is a sugar cook with nuts in it, praline is caramelized sugar and nuts ground together, and a nut bark is tempered chocolate with nuts on it. All three use skills and equipment you already have, which is why they are usually the second product.

The allergen consequence is immediate

Once nuts run on your equipment, every other product sharing that equipment has a cross-contact question. A plain caramel made on the same surfaces is no longer plainly nut free, and the label has to reflect that honestly.

Which is a commercial decision, not just a compliance one

Buyers avoiding nuts are a real market and one that reads labels carefully. Keeping a genuinely nut-free line requires dedicated equipment rather than a thorough clean, and deciding whether to is a strategy question worth making deliberately.

Nuts bring oil, which brings rancidity

A nut confection has a shelf life limited by the nuts rather than by the sugar, and nut oil oxidizes. That shortens the date relative to a plain confection and it means buying nuts fresh matters, which is the same argument the nut butters property makes at length.

And they burn before the sugar does

Nuts added early to a sugar cook scorch at temperatures the syrup tolerates, which is why most recipes add them late. A nut brittle that tastes acrid is usually a timing problem rather than a temperature one.

Where to read more

The nut butters property covers buying nuts, aflatoxin and the supplier questions in detail, and all of it applies here. The sourcing discipline is the same even though the product is nothing alike.

Label the nut variety, not just the word nuts

Tree nut allergies are often specific to particular nuts, so naming almond, pecan or cashew is more useful to the buyer than a general declaration and is expected in this category. It also matters for anybody avoiding peanuts specifically, which are not tree nuts at all.
