What the AI looks for in Cream of Tartar

Egg white stabilization
Use about one-eighth teaspoon per egg white for meringues and angel food cake. It stabilizes the foam so it does not weep or collapse.
Homemade baking powder
Mix two parts cream of tartar with one part baking soda, made fresh as needed. This gives a single-acting powder with no aluminum, useful when you run out.
Texture
It should be a free-flowing white powder. Break up any clumps before measuring. Clumped powder measures inaccurately.

Brands that matter

  • McCormick: Standard supermarket jar.
  • Anthony's: Bulk bags.
  • Frontier Co-op: Bulk spice and baking ingredients.

What to avoid

  • Buying a large bag just for an occasional meringue.

Questions

What can I use instead of cream of tartar?
