The market snack I make when the smoked dougan is in the bag is this one – mala smoked dougan, and this home cook’s version admits in the first step to a special early trip to the market just to photograph the block. A home cook wrote it in five steps with the warning in the fourth: do not fry too long, or the slices turn hard. I made it as written, and it is the crisp-edged, garlic-chili bite of the couch.

Ma la xiang gan (麻辣香干) is mala smoked dougan – smoked dried-tofu slices boiled, quick-fried until their edges crisp, and tossed in a garlic and chili-oil mala coat with sesame.
What Is Mala Smoked Dougan Snack?
This is the five-step snack: smoked dougan – the kind sold as lu xiang-gan at the market – is washed and sliced, then boiled in water just to cover until it boils, and drained. The slices go into oil at seven-tenths heat until their surfaces turn slightly crisp – in batches, and never long, the recipe warns, or they harden. A little oil stays in the pan over low heat with a whole head of minced garlic, then chili oil, oyster sauce, light soy, dark soy, chicken powder, sesame oil, white pepper, and the fried slices all join for the mala coat.
For the caramel cumin snack of the same dried block, my five-spice cumin dried tofu is the sweet-and-savory version.

Over low heat, keep a little oil in the pan and bloom the minced garlic (I used a whole head – I love the garlic); add the chili oil, oyster sauce, light soy, dark soy, chicken powder, sesame oil, white pepper, and the fried slices in one go; toss and cool.
Common Mistakes When Making This Dish
1. Rock-hard slices. Cause: frying too long. Fix: briefly, in batches – the warning. 2. A raw garlic sting. Cause: garlic not bloomed. Fix: low heat first. 3. A heavy, oily coat. Cause: too much oil. Fix: a little for the bloom. 4. A one-note saltiness. Cause: no chili oil or pepper. Fix: the mala balance. 5. Soggy slices. Cause: wet from the boil. Fix: drain well.
Variations
Cooler: Less chili oil. More snack: Sesame over the top. My cold frozen tofu salad is another spiced snack from the same bean.
Frequently Asked Questions
What is lu xiang-gan? Smoked dried tofu – the market calls it lu xiang-gan. Why fry in batches? Crowding steams; and never long, or it hardens. Why a whole head of garlic? The recipe’s generous choice. How long does it take? About 20 minutes. Is it spicy? Yes – mala means numbing-hot, and my silken tofu potage is the calm soup to follow, braised tofu with bok choy the green plate.
How to Serve
Serve cool as a snack or with congee – with five-spice cumin dried tofu, cold frozen tofu salad, and home-style tofu for a snack table, or with red braised tofu and golden pan-fried tofu for contrast.

About the Author & Recipe Development
I am Jason Guo, a Chinese chef who has cooked professionally for more than five years – including time as a head chef – and now runs my own small restaurant in China, where tofu appears on the menu almost every day. This xiachufang cook’s mala smoked dougan is the market snack of my own couch, and the recipe’s fry-it-briefly warning is exactly why the slices stay crisp. I tested it as written. I have not tested the cool version, so that is your experiment, not my claim.
