I made 1-liter almond milk at home, I also brought vanilla essence to put into that but I don't know how much vanilla essence I should include in 1 liter of almond milk.
Can anybody guide me on this? Thank you.
This cannot be answered directly as 1) I don't know how strong your essence is, 2) how rich your almond milk is and 3) Only you know how strong a vanilla flavor you want.
Instead I will suggest an approach, which is to add small amounts and mix it in, tasting as you go until you get the flavor you want. Record how much you add per unit (cup/pint/liter/etc.) of almond milk so you aren't guessing next time.
