Omasum, Quick stir-fry, 68°

Cook Omasum as “Quick stir-fry” until the centre reads 68 degrees. The mark to keep is 68°. Before you pay, check once that the cut named on the package matches the cut on the slip. If the seam of sinew is badly split, change the slip from a short sear to a long cook. Almost no fat — buy for snap and clean smell. At the butcher, open Omasum so the slip shows 68° first, 68 next, and “Quick stir-fry” beside them.

This week, before you enter the butcher, write the cut, the method, and the core temperature at the top of the shopping slip, and at home keep the heat until the thermometer shows that figure. If the grain is coarse, give more time at the same temperature, and do not time a thin slice and a chunk the same way. The order is Omasum, 68°, 68, then “Quick stir-fry”. When the thermometer is done, look again only at 68° for Omasum and leave 68 on the slip.

Do not call the meat done from color alone, and do not read the temperature as a grade score. Check that the core temperature on the slip and the thermometer match, and do not kill the heat before that mark even if the color changes first. If the seam of sinew is badly split, change the slip from a short sear to a long cook. Match Quick stir-fry with 68 at the butcher before you close 68° for Omasum. Cook Omasum as “Quick stir-fry” until the centre reads 68 degrees. The mark to keep is 68°.
