Butter Scotch Tablets

Ingredients

Directions

Make the syrup

  1. Combine sugar, water, and cream of tartar in a copper kettle over a brisk fire.

  2. Boil until it reaches the 'strong crack' stage.

Shape and finish

  1. Remove from heat and stir in the butter and lemon oil quickly with a wooden paddle.

  2. Pour the mixture onto a greased slab and fold in the edges as it begins to harden.

  3. Once cool enough to handle, mold it well and cut off pieces to run through a large tablet machine.

  4. Allow to cool completely and then pack away for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Loaf sugar
Forms the bulk of the candy and sets into a firm, brittle structure as it cools.
Cream of tartar
Acidifies the syrup, helping prevent crystallization so the candy stays smooth.
Butter
Adds richness and a tender, melting texture to the hard candy.

The step that matters

Boiling to the strong crack stage. Sugar syrup must reach the right temperature to set firm when cool. Stopping early leaves a soft, sticky candy, while overcooking makes it bitter and brittle.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, cream, butter):

  1. Vanillafits better
  2. Strawberryfits better
  3. Coconutfits better
  4. Lemonthe original

Fit is the average pairing score against sugar, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
