Low-FODMAP Asafoetida substitute (see notes for more ingredient suggestions)
Use ½ teaspoon in place of every ¼ teaspoon of asafoetida (and adjust to taste)
Notes
Here are some additional options to use as an asafoetida spice substitute
If you are not following a low-FODMAP Diet, you can use garlic powder and onion powder to impart a similar flavor. You can use them each independently, or combine the two. Since hing is so strong, and used in such small quantities, you will want to use a bit more onion and garlic. Start small so as not to over-power your dish.
Powdered or fresh chives - If using dried chives, you can create your own powdered chives by grinding them in a spice grinder or mortar and pestal. Once powdered, start with the same quantity as the recipe calls for asafoetida, then add more to your taste. When using fresh, chop finely and use twice as much as the recipe calls for.
Fresh, powdered or dried leek - use about 3 times the amount of leek in place of asafoetida that the recipe calls for. If using fresh, chop very fine, and be aware that leek will add additional volume your recipe. If you follow a low-FODMAP diet, powdered or dried leek may not be a FODMAP-friendly spice, as the white part of the leek is often included in most products.
Shallots - these are a relative of onions and part of the Allium family. Slice thinly and sauté in butter, ghee or oil. Quantity to use depends on your taste. Dried shallots are also a great option. You can grind these in a spice grinder or use a mortar and pestle to make a powder, to distribute their flavor throughout the dish. Avoid these for low-FODMAP.
Onion paste - puree sautéed onions in a food processor, and add to taste in your recipe - or purchase onion paste online. Skip this one for low-FODMAP.
Garlic scape powder - this is a great low-FODMAP seasoning. Use in a 4:1 ratio for asafoetida substitution.
Garlic flakes - use as a simple substitute. Use 1 teaspoon for each ¼ teaspoon of asafoetida in a recipe. Keep in mind, garlic is high-FODMAP.
Celery seed powder - use twice the quantity as asafoetida in your recipe
