Although many Persians say that shallots sold in markets are raw musir, this is not correct. Shallots sold in markets are basically a form of onion. However, musir, Persian shallots (allium stipitatum) taste and smell more like mild garlic without making your breath garlic’y.
I am not aware of fresh musir sold in markets. However, dried musir is available in Middle Eastern markets.
How to make Mást’o Musir / Yogurt with Persian Shallots
Soak dried musir in a tight lid container for 2+ hours.
Mince 7~9 pieces of soaked musir pieces for every 2 cups of yogurt. Add salt and black pepper to taste, mix and refrigerate overnight for it to meld. It goes well with lavash or any Persian bread.
