FAQ

Can this go in a shake jar?

Yes. Its liquids pour to printed fill-lines, so it can be one of the sauces on a PantryFlex jar.

What do the quantities mean?

This page lists the published recipe in household units (with metric in parentheses). A PantryFlex jar makes a 1.35× batch of it. The jar's printed lines, counts, and QR guide are already scaled to match, so follow the jar or this page, not a mix of both. Amounts in the jar’s ADD row are rounded to the nearest common spoon measure (T = tablespoon, t = teaspoon) so they can be read off the glass.
