- Blackburn's Preserves have been making taste buds sing since 1927. The
flavor and quality is that amazing. Spread some on toast, on your next
peanut butter and jelly sandwich or try some in a recipe. With five
different flavors to choose from, your fridge will be jam packed! And
with Blackburn's unique packaging, these mug-style jars are easier to
handle and make a great addition to your drinkware when the delicious
preserves are gone.
