Mapo Tofu

Variations

• Vegetarian mapo: Use minced shiitake instead of meat for umami.
• Milder: Cut the doubanjiang and chili and skip the peppercorn for kids.
• Mapo eggplant: The Sichuan eggplant version, tofu swapped for eggplant.
• Beef version: Minced beef instead of pork for a richer taste.

Tips

• The dish is named after the tofu and every tip on it is about the sauce. What the tofu actually is, is written on Douhua: stop at the curd and it is douhua, "ladle the curd into a mould and press the water out and it is tofu — pressing is the only thing that separates them." And the curd is not lumps of protein suspended in liquid, it is one continuous gel: "acid gives you lumps; a salt gives you a gel", calcium ions bridging between soy proteins so the whole pot stands up at once.
• Which is the whole reason for nudging the pan instead of stirring. That page's rule for the setting stage is "once it is poured, do not touch it… the network tears, and a torn network does not rejoin", and its serving line is the same fact at the other end of the material — shave the surface in sheets and the smooth faces survive, "dig in with a spoon and the same gel arrives looking like rubble." A block in a pan of sauce is that gel with the water pressed out. A spoon through it is not mixing, it is cutting, and nothing you do afterwards puts it back.
• And blanching it in SALTED water, rather than plain, follows from the same sentence. The gel was stood up by ions in the first place, so a salted bath firms the surface rather than working against it, while plain boiling water pulls soluble solids out of something that is mostly water and leaves it tasting washed. The brief heat also drives a little water out of the outer layer, which is what makes room for the sauce — the tip's "takes on seasoning" is a space problem, not an affinity one.
• It also explains the substitution its neighbours make. Palak paneer lists firm tofu as a one-for-one swap for paneer, and Saganaki sorts paneer as a curd set by acid with the calcium gone, so it "can never re-flow". Both are pressed curds that hold their shape in a hot sauce because they have no elastic network to lose — which is exactly why neither of them melts, and why both are cut before they go in rather than after.
• Doubanjiang is the heart of the flavor — fry it in oil to release the red, fragrant chili oil.
• Blanching the tofu keeps it from breaking and helps it absorb seasoning.
• Add the Sichuan peppercorn (huajiao) at the very end for that signature tingling 'ma' aroma.
• Add the starch slurry in stages to control thickness — all at once turns it gluey.
• Don't stir the tofu — shake the pan or nudge gently to mix.
