IHOP Marinara Sauce
IHOP's marinara is high because it is built on fresh tomatoes and tomato puree.
Most of this is cooked to order, which is the best case for histamine. Even so, a restaurant kitchen preps ahead and holds things warm through a service, so freshness varies more than it would at home. The rating above comes from the chain's published ingredients. If a dish is borderline for you, asking how it is prepared tells you more than the menu does.
This sauce is peeled vine-ripened tomatoes and tomato puree with onion, garlic, oil, and spices.
-
Tomatoes and tomato puree — tomato is a classic histamine liberator, and with both fresh tomato and concentrated puree here, the sauce is high on that alone.
-
Soybean oil — the oil is moderate, but it sits under the tomato, which is what sets the level.
There is no clean way to lower a tomato-based sauce, so a non-tomato option is the better path.
