Chef Chu's Hot & Sour Beef
Recipe from Lawrence C.C. Chu
Two distinct textures — soft and crunchy, plus two distinct flavours — spicy hot and mild, are created using this traditional Hunan recipe. For colour and yet another texture, it is served on top of jade-green broccoli.
Yields:
6 servings
Time Required:
- 15 mins. cooking time
Ingredients:
- 1 lb. (0.45 kg) flank steak, trimmed
Marinade
- 2 tsp.1 (10 mL) light or regular soy sauce
- 2 Tbsp. (30 mL) water
- 1 egg white
- 2 tsp. (2.7 g) corn starch (US/Canada), aka cornflour (UK/other)2
- 1 Tbsp. (15 mL) vegetable oil
- 1 head broccoli, trimmed and cut into bite-size pieces
- Chicken broth (see optional recipe, below)
- Vegetable oil, for blanching
Spices
- 2 tsp. (10 mL) chilli paste
- 2 tsp. (4 g) minced fresh ginger
- 2 large cloves garlic, minced or pressed3
Seasonings
- 3 Tbsp. (45 mL) soy sauce
- 2 Tbsp. (30 mL) dry sherry
- 2 tsp. (2 g) sugar
- 1 green onion, chopped
- 2 Tbsp. (30 mL) red rice vinegar
- Cornstarch paste4
- ½ tsp. (2.5 mL) sesame oil
Preparation:
Cut flank steak against the grain into ⅛ by 1 by 1 ½" (3 x 25 x 38 mm) slices. Combine with MARINADE ingredients in the order listed, mixing well. Let stand for 10 mins.
To water-blanch, cook broccoli in enough boiling chicken broth to cover for 2 mins. Re-move, drain, and keep warm.
To oil-blanch, set wok over high heat for about 1 min. Add 2 cups (475 mL) oil, and heat to 300°F (150°C). Add beef, stirring vigorously to blanch just until redness is gone. Remove and drain.
To stir-fry, remove all but 5 Tbsp. (75 mL) oil from wok. Reheat, swirling wok to coat sides. Add SPICES; stir-fry for 15 secs. until fragrant. Return beef to wok, cooking for 30 secs. Stir in SEASONINGS, mixing well. Sprinkle with green onion and red rice vinegar. Thicken with 1 tsp. (5 mL) cornstarch paste; then stir in sesame oil, mixing thoroughly.
To serve, arrange broccoli on a serving platter, and spoon hot beef over all.
Rich Chicken Broth
A good, rich-tasting chicken broth is essential to Chinese cooking, so, in my restaurant, I make no exceptions. I always use 4-5 lb. (1.8-2.3 kg.) chickens, because I'm preparing food in such volume, but you can use a regular broiler-fryer, if you prefer. I firmly believe a good broth needs no additives. So, why not take a little time (and not much effort), and prepare this chicken broth?
Yields:
8 servings
Time Required:
- 1 ½ hrs. cooking time
Ingredients:
- 1 roasting chicken (4-5 lbs., 1.8-2.3 kg.) or about 4-5 lbs. (1.8-2.3 kg.) chicken bones (wings, neck, back, carcass)
- 4 qts. (3.8 L) water
- ½ white onion, cut up
- 4 knobs fresh ginger, crushed
Preparation:
To par-boil, place chicken (or bones) in an 8-qt. (7.5 L) stockpot. Cover with boiling water, and cook for 5 mins., to get rid of the scum. Pour chicken into a colander, rinse under cold water, and return chicken to pot.
To cook, add water and vegetables. Bring to a boil, reduce heat, and simmer uncovered for about 1 hrs. Occasionally skim surface as needed. Remove from head and cool, then strain well before using.
Author's Notes
As I mentioned, this recipe produces a rich broth that is the basic stock for many of my other soups. If you prefer not to make it, or you don't have the time, always use chicken bouillon (cubes) in water, rather than the less flavourful, canned chicken broth.
Save your chicken bones. You can use them to make broth, instead of a whole chicken.
Since the vegetables are added only for flavour, use tips and ends of onions and knobs of ginger root. I mention this since I was once told by a student that she couldn't find "knobs" of ginger at her market.
If you make broth several hours ahead of serving time, let it cool with the bones still inside. If made several days in advance, try freezing it in ice cube trays; when frozen, store cubes in a sealed freezer bag (1 ice cube equals ¼ to ⅓ cup broth).
1 Quarts, pints, cups, tablespoons, teaspoons, and fl. oz. are as defined in US Customary Units, not to be confused with differing British imperial, "legal", "coffee", Commonwealth of Nations, Canadian, Latin American, Japanese, Russian, or Dutch definitions — further proof that everyone needs the metric system.
2 "Corn starch" is powdered starch processed from the New World grain maize (from Spanish, orig. from Nahuatl), which grain the USA/Canada call "corn", unlike the rest of the English-speaking world, which reserves "corn" to mean cereal grains generically. This starch product, needed here in its customary role as a thickening agent, is called "corn starch" in the US/Canada, but "cornflour" in the UK and most other anglophone lands — not to be confused with whole maize grain: That product — not a thickening agent — is called "polenta", "corn meal", or "corn flour" in the US/Canada, depending on how finely milled, and called "maize flour" in the UK and most other places. Australians should beware that their "cornflour" is starch extracted from wheat kernel, sometimes more-helpfully labelled as "wheaten cornflour". As if that weren't confusing enough, the maize-based thickener may be labelled (in Australia) either as "corn flour" or as "corn starch", so beware. Further, the maize flour product, there, is labelled as "cornmeal".
Note that whole-maize grain is traditionally, in Meso-American cultures of origin, wisely soaked in alkaline solution ("nixtamalised") to increase bioavailability and thereby prevent niacin deficiency (pellagra), among other important benefits, yielding "masa" (lit. dough) aka "masa de maíz" (lit. maize dough), also available in dried & ground form as "masa harina" (lit. dough flour) aka "harina de maíz" (lit. maize flour), and in its unground form, hominy. As further complication, Americans distinguish "corn flour", meaning prepared from maize endosperm only, from "maize flour" for use of whole maize — the former, neutral-flavoured; the latter, much more nutritious.
Origin of the naming mess: Originally, North America shared with Mother England the language's original meaning of "corn" to mean cereal grains generically (from Old English "corn" meaning single seed of any cereal plant, orig. from Proto-Germanic "kurnam" meaning small seed). The colonists got the gift of maize from native peoples, therefore at first calling it "Indian corn". Later, in the USA and Canada, "Indian corn" got worn down to just "corn", while the original meaning of "corn" was lost, locally. "Maize" is thus now the least-ambiguous term in international contexts, though many Americans either don't know that word or reserve it for variants from Latin-American (and Spanish) cooking.
3 Minced is better. Crushing vegetables breaks all of the constituent cellulose-rich cells' walls and has unfortunate consequences to the food's tastes, particularly in the case of garlic, the crushed paste of which easily becomes bitter, lacking flavour nuance, and sometimes picking up a metallic aftertaste.
So, think of this as your motivation to get a nice, really sharp 8" (20 cm) chef's knife for mincing (producing 1⁄16" = 1.5 mm cuts), and a good cutting board.
4 Cornstarch paste is a thin paste made from equal parts of cold water and corn starch. It's essential in many Chinese dishes (but be careful not to over-thicken). Stir just before using. Store covered in the refrigerator for 1-2 days.
