Onions

Use 1 tbsp dried powder per medium onion; lacks moisture and crunch, best in cooked dishes not raw

onion powder substitute
in pie crust.
Onion Powder in Pie Crust adds a spiced or herbal note to the pastry shell. The replacement should be finely ground to blend into the dough cleanly.

adjustment for this dish
Fresh Onions at 0.25 cup per tsp of powder disrupt the flaky lamination because their 89 percent water content hydrates the flour pockets prematurely; grate, dry thoroughly in a towel, and fold in at the pea-size butter stage, reducing ice water by 2 tbsp to preserve cold butter shards.
02
Garlic Powder
10.0best for pie crust1 tsp : 1 tsp
Different but complementary flavor, works in rubs
10.0
adjustment for this dish
Garlic Powder at 1:1 tsp integrates into the flour the same way Onion Powder does, but its finer grind packs tighter; sift with the flour twice before cutting in cold butter, and chill the rolled shell 15 minutes at 38 F so the crimp holds during blind bake.
03
Garlic
10.0best for pie crust1 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 shouldn't touch raw pastry; microplane, sauté in 1 tbsp butter for 90 seconds, cool to 40 F, and cut into the dough with the remaining butter so the flour pockets stay intact and the crust bakes tender.

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 80 percent water that collapses the lamination; mince to 1 mm, sauté until dry (about 4 minutes), cool, and fold in after the ice water so the cold butter shards stay visible and the flaky layers develop during the 400 F bake.
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 visible green to the pale crust; use the white core only, mince fine, wilt in butter for 3 minutes, dry on paper towel, and tuck into the dough at the toss-with-water step to keep the flour pockets cold and the crimp sharp.

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

Onion Rings
10.01 tbsp : 1 tbsp
Crushed dehydrated rings; rehydrate before adding but gives identical flavor

Adds umami depth similar to caramelized onions; use tiny amounts in stews or sauces

Provides savory-sweet depth; best in marinades or soups where liquid is welcome

technique for pie crust
technique
Onion Powder in pie crust must ride along with the flour before the fat goes in, because once you cut in butter to pea-size pieces the dry powder has no second chance to hydrate evenly into the lamination. 5 tsp salt, cut in 8 tbsp butter chilled to 38 F until the largest pieces are pea-size, then drizzle 4-5 tbsp ice water and toss until the dough holds when squeezed.
Unlike scones, where cream hydrates the dough in a single fold, pie crust relies on visible flour pockets and cold butter shards to generate flaky sheets in the oven. Rest the disc 60 minutes at 38 F before rolling between parchment, dock the base with a fork, blind bake at 400 F for 15 minutes with weights, then crimp the edge and finish 10 minutes uncovered so the crust stays tender and the onion aroma stays in the flour-pocket layers rather than bleeding into any filling.
pitfalls to avoid
watch out
Whisk Onion Powder into the flour before cutting in the cold butter; adding it after leaves gritty pockets that won't hydrate into the flaky layers.
watch out
Avoid water warmer than 38 F; warm water softens the butter shards and the lamination collapses into a short, tender-but-dense crust.
watch out
Don't skip docking the base with a fork before blind baking; trapped steam pushes the crust up and pools onion oils in the dimples.
watch out
Rest the disc at least 60 minutes at 38 F before rolling; unrested dough snaps back and the crimp cracks during the final bake.
watch out
Chill the rolled shell 15 minutes before it goes in the oven at 400 F; a warm crust slumps and the flour pockets disappear.
