Fresh-tasting, Italian-style marinara sauce is a winter luxury, so why not try canning your own? It is a process to make this canned version, but it's oh-so worth it as each jar lasts up to a year! You'll love discovering a hidden jar of this sauce in your pantry in January. Vary the amounts of garlic and spices according to your family's taste. Use this as a base sauce and add sausage, ground turkey, and other spices.
