Sweetbread

Why sweetbread is rated low

Sweetbread is low FODMAP. It is the thymus or pancreas of a calf or lamb, and as plain organ meat it is essentially protein and fat with negligible carbohydrate, so there is nothing in the meat itself to push the rating up. That rating is estimated from what sweetbread is made of rather than from a measured serving, and the serving data carries a single rung, "Any typical portion", which reads low. What it does not cover is an unusually large plate, or the flour, milk, cream, stock and onion that classic sweetbread recipes tend to bring along.

What changes your risk

• The dredge Sweetbreads are usually dusted in flour before searing, and ordinary wheat flour is not a low FODMAP coating. Rice flour, cornflour or a gluten free flour gives the same crisp crust.
• The soak Many recipes soak sweetbreads in milk before blanching. Ordinary milk is high FODMAP, so cold water or lactose-free milk does the same job without changing the rating.
• Sauce and braising liquid Cream sauces, shallot, onion, garlic and ready-made stock are traditional partners. Cooking does not break those FODMAPs down, and whatever leaches out of onion or garlic stays in the liquid you spoon over the meat.
• The whole plate A low rating is per serving, not per meal. Sweetbreads served over wheat pasta or with a garlic-heavy sauce add up to a load the meat itself never carried.
• Portion The rating covers any typical portion. A very large helping sits outside what the estimate describes.

What else works

Other plain proteins sit in the same low place for the same reason: veal, lamb, chicken, pork, fish and eggs cooked without onion or garlic. The lookalikes that are not reliably low are the prepared versions: sweetbreads breaded in wheat crumbs or battered in wheat flour, sweetbreads finished in a cream sauce, and pâtés or terrines that bind organ meat with onion, garlic, cream or breadcrumbs. For the savoury base that shallot usually provides, garlic-infused oil, chives, the green tops of spring onions and fresh herbs fill the role.

How to keep it low

Sweetbreads are perishable and are usually bought fresh from a butcher or frozen. Soak them in cold water, blanch them, peel away the outer membrane, then press them under a weight in the fridge so they firm up and slice cleanly. Dust the slices in rice flour and sear them in a hot pan with garlic-infused oil for a crisp outside with no high FODMAP ingredient in sight. For a sauce, reduce a homemade stock made without onion or garlic and finish it with chives, and serve with potato, polenta or rice rather than wheat pasta.

Common questions

is sweetbread low fodmap

Yes. Sweetbread is rated low FODMAP, estimated from what it is made of: plain organ meat that is essentially protein and fat. The serving data reads low at "Any typical portion".

can you eat sweetbreads on the low fodmap elimination phase

Plain sweetbreads fit, as long as the coating, soak and sauce are low FODMAP too. Swap wheat flour for rice flour, milk for cold water or lactose-free milk, and onion or garlic for garlic-infused oil and chives.

are breaded sweetbreads low fodmap

Not reliably. The meat is low, but a wheat flour or breadcrumb coating is not, so the finished dish depends on what the crust is made of.

what to serve with sweetbreads on a low fodmap diet

Potato, polenta, rice, carrots, green beans and baby spinach all sit well alongside them. Keep the sauce free of onion, garlic and cream so the plate stays as low as the meat.
