Description
Acid-driven denaturation of proteins using unripe grape juice.
Technical
Verjus (pH 2.8-3.4) induces partial protein unfolding via protonation of amino groups, while malic/tartaric acids inhibit microbial growth through membrane disruption.
Culinary Significance
Creates translucent cured textures without harsh salinity, ideal for delicate proteins.
