What each ingredient does
- Strained tomato juice
- Forms the flavorful liquid base that the aspic sets from.
- Cornstarch
- Thickens the hot liquid so it can set firm when chilled.
The step that matters
Boil until clear. Cornstarch must be fully boiled to swell and gelatinize; undercooked starch leaves the aspic cloudy and gives it a raw, pasty taste and weaker set.
