CONCLUSIONS BASED ON THE FOREGOING EXPERIMENTS

1. Starch granules must be separated before being used to thicken a

liquid:

(1) By adding a double quantity of cold liquid,

(2) By adding a double quantity of sugar,

(3) By adding a double quantity of melted fat.

2. The liquid which is being thickened must be constantly stirred, to

distribute evenly the starch grains until they are cooked.
