Asafoetida

Asafoetida (called "hing" in South Asian cooking) is dried resin from a giant fennel relative. Raw, it smells aggressively sulfurous — but a pinch bloomed in hot oil mellows into something close to fried garlic and onion. That flavor profile is exactly why it shows up so often in low-FODMAP recipes: it provides the savory allium top-note without the fructans that trigger IBS.

Why it works on low-FODMAP diets

Monash University has tested asafoetida and lists it as low-FODMAP at typical culinary doses (a small pinch — about 1/8 teaspoon). Most commercial hing is cut with wheat flour, though, which is itself a fructan source — gluten-free versions cut with rice flour are available and worth seeking out for celiac or strict-fructan-avoidance contexts.

How to use it

Asafoetida is almost always bloomed in oil at the start of cooking, never added raw. The volatile compounds responsible for the harsh smell break down quickly with heat, and what remains is a deep savory note. Common in Indian dals, lentil dishes, vegetable curries, and pickles. A 100g jar can last a household a year — tiny amounts go a long way.
