Identify your use: baking (cookie/cake/muffins) vs thickening (sauce/cream).
Swap by the ratio in the table; for cassava/coconut, start with the listed amount first (they absorb more).
Mix and assess texture after 30–60 seconds: if it looks dry/grainy, add small splashes of water/milk (1 tablespoon at a time).
For thickening, simmer 1–2 minutes longer than you think you need, then check gloss and thickness.
If you miss the gentle sweetness of tigernut flour, add a small pinch of sugar/honey or a teaspoon of vanilla.
