Croquant Paste for Covering Preserves

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the paste

  1. Dissolve the sugar in enough cold water to make a paste with the flour.

  2. Knead and beat the mixture until smooth.

Shape and cut

  1. Roll the paste to the size of the croquant form and about ½ inch thick.

  2. Grease the form with beef suet and press it into the paste to cut the pattern.

Bake and finish

  1. Bake in a 300°F (150°C) oven.

  2. Brush the paste with beaten egg white and sprinkle fine sugar on top.

Cover and store

  1. Gently remove the paste from the tin while warm and place it over the fruit to cover.

  2. Store the cover in a dry place for reuse.

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

What each ingredient does

Flour
Forms the main structure of the paste, which sets firm as it bakes.
Cold water
Hydrates the flour so it forms a smooth, workable paste.
Sugar
Adds sweetness and helps the baked surface turn crisp.
Egg white
Brushed on top to give the baked paste a glossy, set finish.

The step that matters

Bake in a low oven. A low oven at 300°F dries the paste slowly so it sets firm and crisp while staying pale. Higher heat would brown the surface before the interior dries, so the paste would be less even.
