oregano is a leader in causing heartburn in general…
use less, less heartburn.
that is simply put, there are other causes of heartburn and indigestion in different people at different times…
spices, fat, sugar, peppers can all casue it…
I remember a story that Tom Lehmann told about a pizzeria in a mall that was losing business to the older people because as much as they liked his pizza, they got heartburn so they ate his pizza less frequently…
Tom, knowing about the plight of oregano, advised him to reduce/eliminate his oregano in his sauce, advertise a “mild” pizza…the old folks came back and he did not lose the younger ones…ie more business… Tom, correct me if I got the story wrong
as for me, I use no oregano, 2 grams sweet basil, 7 grams black pepper, 19 grams salt, and 10 grams lemon juice to a #10 can of 6N1 Escalon all purpose crushed tomatoes…
I sprinkle a very little oregano on top of the pizza as it comes out of the oven, as well as a parm/romano grated cheese blend…
I have a “seasoning bar” loaded with enough spices and herbs to start a fire that they can make it as spicey as they like, and some do…
I have many comment to the effect "god pizza and no heartburn, like “XYZ”, thanks ?
…if you are mostly serving kids and younger people, ie Chuckie Cheese, I think you could load it up with oregano, customers would like it and not complain about heartburn.
I am in a snowbird retirement resort,
hope that helps,
