Mixed nut

Recipe gives grams; mixed nuts weighed directly.

Instead of Mixed nut

Cashew nut
Use the same weight; toast lightly or fry briefly. It gives a creamy richness similar to mixed nuts.
Almond
Use the same weight; blanch and peel for a softer texture, or chop and toast for crunch.
Peanut
Use the same weight; roast and rub off skins. Flavour is stronger and less sweet, so use slightly less if you like.
