Swerve and Stevia
Swerve and Stevia are natural sweeteners that have zero carbs. Swerve comes in Confectioners and Granular form. Stevia should be pure and free of additives.
The manufacturer for Swerve indicates that 1 tsp of Granular Swerve corresponds to 1 tsp of granular sugar. Since Confectioners it is less dense it takes 1 1/2 tsps of Confectioners Swerve to substitute for 1 tsp of granular sugar. For recipes on this site that specify a sugar equivalent be sure to add 50% if you are using Confectioners Swerve.
The manufacturer for Stevia indicates that 1 tsp of Stevia is equivalent to 1 cup of sugar and is far less expensive than Swerve. Some people experience a strong bitter aftertaste with Stevia but have no problem with Swerve. Those who are allergic to plants in the Compositae or Asteraceae family (such as chrysanthemums, marigolds, ragweed or daisies) may have an allergic reaction to stevia. These side effects are rarely experienced.
I use Stevia unless sugar adds significant bulk to a recipe as it does in Butter Cookies. In this case I used Confectioners Swerve to avoid a gritty consistency. Here are links to Swerve, Stevia, and some mini spoons so you can precisely measure small amounts of Stevia:
