Choosing the right swap

Start with Gelatin, then adjust for what your recipe needs.

  • Match the substitute’s context tag to your recipe, a swap that shines in baking can fall flat in a sauce.
  • Respect the listed ratio. Many swaps are not 1:1, and over- or under-dosing is the most common reason a substitution disappoints.
  • Working around a diet? 2 of these options carry dietary tags, filter by your need. Browse by diet
  • Need the opposite lookup? Browse other Thickeners ingredients with overlapping swaps. More Thickeners
