Frozen raw mushrooms are cleaned mushrooms frozen without a preheating step, the variant a Japanese forest-volunteer manual describes beside its cooked version.

Steam-blanched frozen mushrooms are whole, button, quartered or sliced mushrooms given a short steam treatment, cooled promptly, packed with headspace and kept frozen.

Pan-heated frozen mushrooms are cut mushrooms cooked briefly in margarine or butter in an open pan, cooled and frozen as a partly cooked ingredient for later meals.

Whole or sliced domestic mushrooms packed hot in jars with fresh water and processed in a pressure canner, the tested home method for a low-acid vegetable.
