radishes substitute
for baking.
Baked radishes lose 60-70% of their isothiocyanate heat as the volatile sulfur compounds break down above 140F, leaving a mellow, almost-potato note. In quick breads or savory tarts they donate moisture (94% water raw) and a faint pink crumb, but contribute zero gluten and no leavening. Substitutes here are judged on water release during a 25-30 minute bake at 375F, on whether they brown rather than steam, and on whether their pigment survives the oven without bleeding into the surrounding crumb.

adjustment for baking
Sub at 1:1 cup. Turnips bring slightly more starch (6.4 g vs radish 3.4 g per 100 g) so the crumb sets firmer in a 375F bake. Dice 6 mm and pre-roast 8 minutes to drive off surface water before folding into batter, otherwise the crumb gums.
02
Fennel
10.01 cup : 1 cup
Thin sliced fennel adds anise crunch to salads
10.0
adjustment for baking
Sub at 1:1 cup. Fennel bulb adds anise via anethole, which survives a 375F oven intact and perfumes the whole loaf. Slice 3 mm; its higher fiber holds shape during 30-minute bake. Pre-toss with 1 tsp lemon juice to keep the cut surface from browning gray.
03
Cabbage
10.01 cup : 1 cup
Shredded for peppery crunch in tacos and slaws
10.0
adjustment for baking
Sub at 1:1 cup, shredded fine. Cabbage releases more water (92% vs 94%, but in larger surface-area bursts) so press in a towel for 10 minutes before folding into batter. Sulfur notes mellow at oven temps above 350F into a sweet brassica register, not peppery.

Beets
7.51 cup : 1 cup
Roasted radishes turn mild and tender
7.5
adjustment for this dish
Sub at 1:1 cup, grated raw. Beets bring 9.6 g sugar per 100 g, about 5x the radish, so cut added sugar in the recipe by 15-20% or the bake leans cloying. Pigment bleeds magenta into pale crumb; lean into it or pre-roast and peel to mute it.
05
Cucumber
7.51 cup : 1 cup
Peppery raw but mild when cooked; slice very thin
7.5
adjustment for this dish
Sub at 1:1 cup, peeled and seeded. Cucumber holds 96% water vs radish 94%, salt 1 tsp per cup and drain 20 minutes before use or the crumb stays wet at the 30-minute mark. Flavor turns subtle and grassy under heat, almost zucchini-like.
06
Kohlrabi
7.51 cup : 1 cup
Mild crunch, slice thin for salad garnish
7.5
adjustment for this dish
Sub at 1:1 cup, peeled and diced 6 mm. Kohlrabi has lower water (91%) and higher fiber, so it survives a 375F bake without slumping. Flavor reads as broccoli-stem-meets-apple after baking. No pre-treatment needed; fold straight into the batter cold.
07
Celery
7.51 cup : 1 cup
Fresh crunch for salads and crudite platters
7.5
adjustment for this dish
Sub at 1:1 cup, diced 4 mm. Celery's stringy ribs soften but never fully melt in a 30-minute bake; pre-mince or peel the outer fibers. Carries an aromatic apiol note that pairs with cheese or onion in a savory tart. Holds shape better than radish in quick breads.
08
Horseradish
5.01 tbsp : 3 tbsp
Grate fresh, milder so use more
5.0
adjustment for this dish
Sub at 1:3 tbsp - three times the volume because heat destroys 80% of horseradish's allyl isothiocyanate within 10 minutes above 160F. Grate fresh and stir in last. Best in savory rye or pumpernickel where a residual peppery tail rounds out caraway.
