Instant ClearJel is a pre-gelatinized, modified waxy-maize starch — the pastry world's favourite no-cook thickener for fruit fillings. It thickens instantly on contact with cold liquid, sets a clear, glossy gel, and, crucially, holds that set through the oven and the freezer without breaking down. That combination makes it the standard for pre-baked and frozen pie fillings, where a cooked cornstarch slurry would weep or turn cloudy.
