I got two layers of meat from the shank and two layers of white chicken. In a glass of broth, dilute the instant gelatin (if ordinary, then the gelatin solution is prepared in accordance with the instructions on the package). Fill our meat with gelatin broth, pierce it in several places with a knife (so that our broth is evenly distributed), carefully seal the meat with a tablespoon, if necessary, add more gelatin broth (so that the liquid just appears on the surface of the meat).
Close the terrine with the ends of the film hanging from the mold and put it in the refrigerator for 8-10 hours (I put it overnight).
