FAQ

Can this go in a shake jar?

No — this one needs a blender or stove, so make it from this page. Jars only carry pour-and-shake sauces — its companion jar is below.

What do the quantities mean?

Amounts follow the published recipe in household units (with metric in parentheses). On a jar, every sauce scales to the same fill height.
