adjustment for this dish
Fresh Onions at 0.25 cup per tsp of powder deliver deeper body because their 89 percent water content releases into the simmer; dice fine, sweat in 1 tbsp oil for 8 minutes until translucent, then add stock and reduce uncovered to depth rather than adding raw to cold broth.
02
Garlic Powder
10.0best for soup1 tsp : 1 tsp
Different but complementary flavor, works in rubs
10.0
adjustment for this dish
Garlic Powder at 1:1 tsp blooms in hot oil for 20 seconds before stock, faster than Onion Powder's 30-second bloom, because its finer particles burn sooner; watch for the first aroma lift, then deglaze with stock immediately to preserve the warm sweetness during the 25-minute reduce.
03
Garlic
10.0best for soup1 tsp : 1/4 tsp
Stronger pungent bite; use 1/4 tsp garlic powder per tsp onion powder, or mince one small clove
10.0
adjustment for this dish
Fresh Garlic at 0.25 tsp per tsp of Onion Powder needs 60 seconds of sauté in oil after the aromatics to mellow the raw alliin; add to the simmer in the last 10 minutes rather than at the start, or the reduction concentrates a sharpness that cuts through the broth body.

Shallots
10.01 tbsp : 1 tbsp
Fresh minced shallot is milder-sweeter than powder; use 1 tbsp fresh per 1 tsp powder
10.0
adjustment for this dish
Shallots at 1 tbsp per tsp bring mild sweetness and 80 percent water; mince, sweat in oil for 5 minutes until translucent, add stock and bay, and reduce for 25 minutes so the warm depth builds without the need to skim as much foam at the 10-minute mark.
05
Leeks
10.02 tbsp : 1 tbsp
Minced white of leek for mild onion flavor; cook briefly before adding to recipe
10.0
adjustment for this dish
Leeks at 2 tbsp per tsp of powder add sweet body; use white and pale green, mince to 2 mm, sweat in butter for 6 minutes until silky, then add stock and simmer 25 minutes to thicken the broth without the sharpness that raw alliums bring to a late addition.

Chives
10.01 tbsp : 1 tbsp
Much milder and grassier; works in dressings and dips but lacks depth for rubs

technique for soup
technique
Onion Powder is the one place in this ingredient set where a 20-minute simmer actually improves the flavor, because the aromatics steep into the broth and build body without the need to sauté raw alliums. Bloom 1 tbsp powder in 1 tbsp hot oil for 30 seconds before adding stock so the volatiles open, then add 6 cups stock, a bay leaf, and your vegetables and simmer uncovered for 25 minutes to reduce by roughly 15 percent and concentrate depth.
Unlike an omelet, which gets 90 seconds of contact, soup benefits from slow extraction, so the same 1 tsp per serving delivers twice the perceived flavor here. Skim any foam at the 10-minute mark, stir every 5 minutes to prevent scorching at the pan rim, and season with salt only at the end since reduction multiplies saltiness.
If the broth tastes sharp after reducing, temper with 1 tsp cream or a splash of stock to round the warm, sweet onion note.
