Sauce in deep-frozen IQF pellets
To decorate and to flavour stuffing
(firm texture when cold in order to have a good resistance at cutter-mixing and
thick texture when hot to avoid leakage).

Thick sauce in pouches
Almost heat-stable sauce to inject into the product. Does not leak when reheated on the grill.

Sliceable sauce or garnish
Burger sauce, onion-gherkin garnish
to put on a frozen hamburger.
Slice of sauce (tomato/onion) to put between two beef burgers.
