Notes
CHECK YOUR YEAST expiry date! The problem because most people don’t bake with yeast very often, and yeast does go off! If your yeast is past its expiry date OR you’ve kept it in hot humid conditions (instead of fridge or freezer), your dough will not rise.
Yeast test if you’re concerned: in tiny bowl, mix 2 tbsp very warm tap water with pinch of sugar and 1/4 tsp yeast. Leave in very warm place for 5 – 10 min. If surface gets foamy like the below, your yeast is alive and fine to use.
