Stewart's publishes a full ingredient statement for every one of its 61 ice cream flavors and nothing at all for its hot-food counter, so this rating describes the ice cream: 36 of 61 flavors carry a seed or tropical oil in a mix-in, and all 61 carry a synthetic additive, with polysorbate 80 in 55 of them and no clean flavor at all, including plain vanilla. Their own plant-tour page is unusually candid that the hot entrees are cooked in a central kitchen and trucked out and that the tenders, hot dogs and bread are bought in.
Rated 2026-09-06. SCOPE MATTERS HERE: Stewart's is a clean split. All 61 ice cream flavors at stewartsshops.com/ice-cream/flavors/<slug>/ carry a real ingredient statement in the HTML; the entire hot-food, deli and pizza menu publishes nothing at all. seed_oil=some at 0.5 is a FLOOR over the documented half - 36 of 61 flavors name a seed, vegetable or tropical oil in a mix-in, while the 25 plain-base flavors (vanilla, chocolate, strawberry, coffee, the gelati, the sherbets) contain no oil at all. additives=all covers the ice cream only, and there it is total: 61 of 61 carry a synthetic additive, with polysorbate 80 in 55, carrageenan in 59 and an FD&C dye in 17. There is no clean flavor, including plain Vanilla. nova=all is the strongest first-party finding: their own plant-tour page says the hot entrees are cooked in a central kitchen, "We distribute 75% of what we sell in our shops", and chicken tenders, hot dogs and bread are bought in. plastics NULL. Emailed for the fryer oil.
