What oil does Kopp's Frozen Custard fry in?
Kopp's Frozen Custard cooks with Deep-fries French fries and onion rings in separate fryers, though the oil is filtered and reused between them (per a gluten-free cross-contact note, not a fryer-oil brand statement). No official source names the specific oil; industry-default assumption for a Midwest burger-and-custard drive-in is a canola or soybean oil blend, unconfirmed..

Why the frying oil matters
Most fast-food chains fry in seed oils like soybean, canola, corn, or a blend of them, which are high in polyunsaturated fat (PUFA). A handful still use beef tallow or other stable fats, which are far lower in PUFA. The oil a kitchen fries in is the single biggest driver of how much seed oil ends up on your plate. See the full breakdown on the Kopp's Frozen Custard report card, or where it lands on the Seed Oil Index.
