1 sachet of vanilla paste is equal to just over 2 teaspoons of
vanilla paste, as the paste is concentrated the ratio is 1 teaspoon
paste to 4 teaspoons vanilla extract/essence. So you would need 8
teaspoons of vanilla essence to 1 sachet of vanilla paste. Hope
this helps. Vanilla paste is very concentrated (especially if
you're using chef strength) so for every 1 teaspoon of vanilla
essence your recipe calls for, use only 1/4 teaspoon vanilla
paste.
