There was an infamous wing of a Massachusetts prison where the good fellas cooked up feasts. Concord maybe. They has hot plates rigged up and were allowed to bring in shrimp and lobster via the commissary. They had tomato sauces simmering for hours on Sundays
Henry’s book has the great “cooking in prison” recipes...like “Penitentiary Sauce” and “On The Run Pasta”.....and Witness Protection Recipes (living in Nebraska and Seattle)....I gave my brother in law the book for his birthday and he hasn’t gone a weekend without making one of his recipes.
