Mushroom and Lime Broth with Snow Peas, Basil, and Brown Rice
A sharp, chile-flecked broth of mushrooms, ginger, and burst cherry tomatoes finished with a great deal of lime, poured over brown rice with snow peas, tofu, and torn basil.
Why You'll Love This Recipe
I built this one around lime, which is unusual for me, because most sour soups I love use more of it than seems sensible and are better for it. Three tablespoons goes in off the heat, all at once, and it changes the broth from pleasant to alive. Ginger cut into matchsticks rather than coins is the other decision that matters, since you get little hot flecks of it in nearly every spoonful. The rest is fast and forgiving: mushrooms, halved cherry tomatoes, chile, garlic, and a pot of broth that is ready in fifteen minutes.
It eats sharp and hot and a little bit slippery. The mushrooms give up their liquid and go dark, the tomatoes collapse into soft skins and sour juice, and the snow peas stay so green and squeaky that they seem to belong to a different dish. Brown rice goes in the bowl first, and by the time you are halfway down it has drunk enough of the broth to have become the best part. Tofu cubes are there to soak up chile and lime, which they do better than anything else in the pot.
A flat afternoon, the kind where nothing tastes like much, calls for food that wakes your mouth up. It is also what I cook when the vegetable drawer is nearly empty, because mushrooms and a handful of snow peas and half a carton of cherry tomatoes are usually findable. Cook the rice ahead or use a pouch, and lunch takes under half an hour from the moment you pick up a knife.
Ingredients
- 5 cups low-sodium vegetable broth
- 12 oz mixed mushrooms (cremini, shiitake, or oyster), torn or sliced thick
- 1 1/2 cups cherry tomatoes, halved
- 2 cups cooked brown rice, warm
- 7 oz firm tofu, drained and cut into 3/4-inch cubes
- 7 oz snow peas, strings pulled off
- 3 tbsp fresh ginger, peeled and cut into thin matchsticks
- 4 garlic cloves, thinly sliced
- 2 jalapenos or 3 small red chiles, sliced into rings
- 3 tbsp fresh lime juice, from 2 limes, plus wedges for the table
- 1 tbsp low-sodium soy sauce
- 1 tbsp avocado oil
- 2 tsp toasted sesame oil
- 3/4 cup Thai basil leaves, torn if large
- 1 cup cilantro leaves and thin stems, chopped
- 6 scallions, sliced thin
- 1 tbsp sesame seeds, toasted
Instructions
- Start the mushrooms dry: Set a wide pot over medium-high heat and add the mushrooms with no fat at all. Let them sit for three minutes without stirring while they squeak and give up their water, then stir and cook two minutes more, until the liquid has boiled off and the edges are browning. Cooking them dry first is what keeps them from tasting waterlogged later.
- Add the aromatics: Push in the avocado oil, the ginger matchsticks, the garlic, and half the chile rings, and stir for one minute until they smell sharp and sweet. Add the halved cherry tomatoes and press a few against the side of the pot with the back of a spoon so they start to release their juice.
- Simmer the broth: Pour in the broth, bring it up to a simmer, and cook for six to seven minutes. The tomatoes should slump and split, the broth should go faintly orange, and the mushrooms should be fully tender. Taste it now, before anything sour goes in, so you know what the lime is about to change.
- Add the tofu and snow peas: Turn the heat to low and add the tofu cubes and the snow peas. Give them two minutes, no more. The peas should still be bright green and squeaky when you bite one, and the tofu just heated through. This is the point where boiling the pot would cost you both textures.
- Finish with lime and serve over rice: Take the pot off the heat and stir in the lime juice, the soy sauce, and the sesame oil. Spoon warm brown rice into four bowls, ladle the soup over it, and top with the basil, cilantro, scallions, remaining chile rings, and sesame seeds. Put the lime wedges on the table for anyone who wants it sourer, and some people will.
Variations
- Lemongrass and lime leaf: Add a bruised lemongrass stalk and two lime leaves with the broth and fish them out before serving for a rounder, more perfumed sour soup.
- Napa cabbage: Stir a few handfuls of shredded napa cabbage in with the tomatoes for a softer, sweeter bowl with more bulk.
- Corn and basil: Add a cup of corn kernels with the broth for pops of sweetness against all that lime.
- Crisp tofu: Fry the tofu cubes in a little oil until golden before adding them, so they hold their edges under the hot broth.
Storage & Leftovers
The soup keeps four days sealed in the refrigerator, though it is at its best on the first day, when the lime is still sharp and the snow peas still have their snap. Keep the rice in its own container so it does not swell and go pasty in the broth, and add fresh herbs when you reheat rather than storing them in the liquid.
Warm it in a saucepan over medium heat until it steams, three or four minutes, and stop there. A hard boil turns the snow peas olive and softens the tofu into something crumbly. Squeeze a fresh wedge of lime over each reheated bowl, since acid fades in the cold and that one squeeze puts the whole thing back where it started.
It freezes for up to two months, but freeze the broth, mushrooms, and tomatoes only, before the peas and tofu go in. Both of those come back limp from the freezer. Thaw overnight, bring to a simmer, and add fresh snow peas, tofu, lime, and herbs in the last three minutes for a bowl that tastes newly made.
Notes & Tips
- Lime goes in with the burner off: Simmered lime juice turns dull and slightly bitter within a minute. Off the heat, all at once, is where its sharpness survives.
- Matchstick the ginger: Coins perfume the broth and get pushed aside. Matchsticks put a bright hot fleck of ginger into most spoonfuls, which is what this bowl wants.
- Halve the tomatoes, do not quarter them: Halves hold together long enough to slump and split on their own, which is where the sour, jammy pockets come from. Quarters dissolve into pulp.
- Save half the chile for the top: Chile simmered in broth gives even background heat. Chile added at the end gives you sharp bites of it, and you want both.
Nutrition & Mindful Eating
- Mushrooms, tomatoes, snow peas, and brown rice each pull in a different direction, and the bowl works because of it. The mushrooms make the broth savory, the tomatoes make it sour and sweet, the snow peas keep something crisp in every bite, and the rice underneath turns a bowl of soup into lunch.
- Mushrooms cooked dry first concentrate their own flavor rather than diluting it, and they carry potassium, selenium, and B vitamins along with the glutamates that make a quick broth taste long-simmered.
- Cherry tomatoes split in the heat and release lycopene along with their juice, and cooking is what makes that pigment easier for the body to take up. The little bit of oil in the pot helps it along.
- Brown rice keeps its bran layer, which is why the grains stay separate in liquid rather than dissolving, and where its fiber, magnesium, and slow-burning starch come from.
- Lime, ginger, chile, and basil all arrive late or off the heat, and that timing is the reason they taste so loud. Vitamin C is fragile in a hot pot, so juice squeezed in at the end keeps more of it, and the same is true of the fresh herbs piled on top.
- As you eat, pay attention to the moment the lime hits the back of your tongue and the rice starts to swell with broth, and let the bowl cool enough that you have to take it slowly.
Frequently Asked Questions
How sour is this meant to be?
Properly sour, the way a good hot and sour soup is. Three tablespoons of lime across four bowls reads as bracing rather than puckering, and it is balanced by the sweetness of the tomatoes and the earthiness of the mushrooms. Start with two tablespoons if you are unsure and add the third after tasting.
Which mushrooms work best?
A mix is ideal. Cremini give body and color, shiitake give a deeper savory note, and oyster mushrooms tear into ribbons that go silky in broth. Any single one of them alone makes a good bowl, so buy whatever looks freshest and skip the ones with damp, dark gills.
Can I skip the rice?
Yes, and you get a lighter, more soup-like lunch. If you do, add another handful of mushrooms and a few more snow peas so the bowl still has something to chew. Cooked rice noodles are the other direction to go, coiled in the bowl and the hot broth poured over.
Why cook the mushrooms with no oil?
Mushrooms are mostly water, and oil added at the start makes them steam in their own liquid and stay pale and squeaky. A dry pan drives that water off first, and then the browning happens quickly once the oil goes in. It takes five minutes and changes the whole broth.
