FlashSteam Difference: At Hunt's, we're proud to say that the only thing between our farms and your family's table is simple hot water. Why? Because we only use FlashSteam to peel our tomatoes. That means no chemicals, like lye (Lye peeling is generally recognized as safe by the FDA and has no adverse effects on the healthfulness of tomatoes), are ever used when peeling Hunt's tomatoes. We just think it's the right thing to do. All natural. Non GMO. Non BPA liner. Gluten free. No artificial ingredients or preservatives. It's good to be different. Recipes at Hunts.com. Food you love.
