Stage 1 - Pressing (20-60 minutes)
Firm tofu is packaged in water significant water content that occupies space inside the tofu's protein structure. Pressing physically squeezes this water out, creating space that BBQ marinade can subsequently occupy.
The tea towel technique, Lay the towel flat on a plate. Place the tofu block on one side, fold the towel over the top. Place a cutting board on top. The towel absorbs water as it's pressed out move the tofu to a dryer area of the towel periodically to maintain absorption.
20-30 minutes produces good results. Up to 1 hour produces the most thoroughly pressed tofu. Don't exceed 1 hour with moderate pressure longer pressing with too much weight can cause the tofu to lose structural integrity entirely.
Stage 2 - Baking at 425°F (20-22 minutes)
This step is the technique breakthrough that most home cooks skip and shouldn't. Baking the pressed tofu before marinating creates:
Exterior structure- The oven heat forms a slightly firmer, more developed outer layer that holds the tofu together during skewering and grilling. Raw pressed tofu can still tear during skewering; pre-baked tofu handles this with confidence.
Improved marinade absorption- The baking process opens the tofu's protein structure slightly, creating more surface area for the BBQ sauce to penetrate. Warm tofu tossed in BBQ sauce absorbs it more quickly and thoroughly than cold raw tofu.
Cut the tofu into 32 pieces - approximately ½ inch cubes. Spread in a single layer on the parchment-lined sheet pan. Bake for 20-22 minutes until slightly golden but still soft not dried out, not fully crisped, just developing some golden color.
Stage 3 - BBQ Marinating (30 minutes to 8 hours)
Transfer the warm tofu from the oven directly into a bowl. Pour the full ½ cup of BBQ sauce over the warm tofu and stir immediately. The warm tofu absorbs the sauce much more rapidly than cooled tofu would.
Cover and marinate for at least 30 minutes the flavor development at 30 minutes is adequate. At 4-8 hours (do this the morning of your BBQ), the flavor is genuinely extraordinary every cube has absorbed smoky, sweet, slightly bourbon-flavored sauce throughout.
Reserve the remaining marinade sauce for basting during grilling.
