Sweet spreads, and where they stop being low moisture
Updated
On this page7
Chocolate and nut spreads are in the same family
Fat continuous, low moisture, separating if unstabilized, and carrying the same kill-step question. Cocoa and milk solids add their own supply chain and their own allergen line, and the production logic is unchanged.
Sugar has to be ground in
There is no water for it to dissolve into, so granulated sugar stays as crystals and the product is gritty. This is the same problem the smooth nut butter page describes, and in a sweet spread it is much more noticeable because the buyer expects a confection texture.
Where water changes everything
Honey, fruit purée, syrup or any wet addition raises the water activity. Enough of it and the product is no longer a low-moisture food, which means something can grow in it and the entire preservation argument this property rests on no longer applies. That is not a small reformulation.
So measure, do not assume
If you are adding anything wet, the water activity of the finished product is a question to answer rather than estimate, and it may push the product into a different category with a different process behind it. The jams and the syrups properties are where that logic is worked through.
Tempering is a different craft again
A spread that sets firm, or anything involving chocolate that has to temper, is confectionery rather than a nut butter. Worth naming so the boundary of this property is a decision rather than an omission.
The allergen list grows quickly
Milk solids in a chocolate spread, soy lecithin as an emulsifier, and whatever nut is in the base. A sweet spread typically carries more declarable ingredients than a plain nut butter, and each one attaches to every other product sharing the line.
