Why This Recipe Works?
Pressing firm tofu under a weight presses out pockets of water, which collapse to form layers of protein with a meat-like texture. Marinating the tofu in ingredients rich in amino acids such as soy sauce, sake, and konbu tea imbues the tofu with meaty umami. Tearing the tofu into irregular chunks and dusting it with potato starch makes this plant-based Karaage visually identical to Karaage made with meat. Double frying the tofu creates a lasting extra crispy crust.
Ingredients for Tofu Karaage
Firm Tofu - There are two ways to make tofu. The first is to mix coagulant into soy milk and then steam it in a mold. This makes a custardy style of tofu that’s often known as soft or silken tofu. This style of tofu is too soft and will not work for this recipe. The second method is to curdle soy milk by heating it with a coagulant and then capture the curds and pressing them into a mold, like cheese. This process makes firm tofu, and the firmness is determined by how much water is squeezed out of the curds while they’re still hot. To get the best texture for this vegan Karaage, you want to use tofu that’s on the softer side of firm tofu (firm as opposed to extra firm). You can also probably get creative here and use a different alternative protein, but I’ve worked out a process that gives the tofu a texture that’s juicy on the inside and firm and meaty on the outside. Sake - Sake is added to Japanese food for its amino acid content, not for the alcohol (most of which evaporates during cooking). This creates the taste of umami. You can learn more about the science behind it here. Soy Sauce - Soy sauce not only seasons the Karaage, but it is also another good source of amino acids. Konbucha - I know this sounds like the tangy fermented tea that everyone loves, but Konbucha in Japan is a savory “tea” made from kelp (it’s really more like a clear stock). The theory is that someone got the translation mixed up when they brought the concept to the US, and the name stuck. In case you were wondering, the name for the fermented tea in Japan is Koucha Kinoko, which literally translates to black tea mushroom. Since tofu has a much lower concentration of glutamic acid than meat, adding Konbucha is an excellent natural way of bumping up the umami-producing compound. If you can’t find it, some good alternatives are 2 teaspoons of nutritional yeast or 1 teaspoon of shiitake or porcini mushroom powder. Ginger - Ginger is a core component of the taste of Karaage. I like to keep the addition relatively subtle, so I don’t add very much, but you can add more if you like. Garlic - I don’t usually add garlic to my meat-based Karaage because it covers up the taste of the chicken, but for tofu, covering up the soybean flavor is a good thing. Potato Starch - The light crispy shell around Japanese fried chicken is created by coating it in starch. Specifically, you want to use potato starch. Cornstarch will work in a pinch, but the texture is heavier and more crunchy than crispy. It’s kind of like the difference in texture between a potato chip and corn chips. In the US, the most common brand of potato starch is Bob’s Red Mill.
How to Make Tofu Karaage
To press the tofu, put it on a wire rack set on a tray. If you don’t have a wire rack, a relatively flat-bottomed strainer or colander will work. Place another tray or plate on top of the tofu, and then balance some weight on top. If you are using a strainer, you may need to use a bowl on top of the tofu. You want to put as much weight onto the tofu as you can without smashing it up. Let this sit for about an hour to press out the excess water. To make the marinade for the Karaage, add the sake, soy sauce, konbucha, and garlic to a bowl and whisk everything together. When the tofu is done pressing, tear it into irregular bite-sized pieces and place them in the marinade. You want to try and get rid of any hard corners in the tofu. Gently fold the tofu and marinade together to make sure it’s evenly coated but be very careful not to break the tofu up any further, or your pieces will be too small. Let this marinate for at least 30 minutes. While you’re waiting, prepare a wire rack by lining it with a few sheets of paper towels. Next, add 1 ½ inches of vegetable oil to a heavy-bottomed pot (make sure the sides go up at least 5-inches to prevent overflowing). Preheat the oil to 340 degrees F (170 C). When you’re ready to fry the tofu, drain off any excess marinade, and then roll each piece of tofu in the potato starch to give it an even coating. Dust off the excess starch by tapping the pieces against the side of the bowl and then lower them into the oil. Flip the tofu over after the crust sets to ensure they brown evenly. After about five minutes, the Tofu Karaage should be light brown in color and crisp. Transfer it to a plate or bowl and set it aside (there’s no need to drain them on paper towels since you’re going to fry it again). Increase the heat of the oil to 355 F (180 C). When the oil is up to temperature, add all of the Karaage back in and fry a second time until the crust is very crispy and golden brown. This should take another four to five minutes. When the Tofu Karaage is done, drain it on the paper towel lined rack and serve immediately with wedges of lemon.
Serve this With
I like to serve this with a variety of seasoned vegetables like my Smashed Cucumber Salad, Pickled Sushi Ginger, or Simmered Kabocha. It may seem odd to double up on Tofu, but this also goes well with Hiyayakko because it’s such an extreme contrast of tastes and textures from this crispy karaage.
