What home-cooked dishes are considered a basic test of someone's cooking skills in your country?
In China, some classic examples would be braised pork belly, stir-fried pork with green peppers, stir-fried leafy greens with garlic, hot-and-sour shredded potatoes, and tomato and egg stir-fry. They’re all simple everyday dishes, but making them really well still takes some basic cooking skills.
Braised Pork Belly — The pork should be tender and flavorful, with a rich, glossy sauce.
Stir-Fried Pork with Green Peppers — The pork should stay tender, while the green peppers should remain slightly crisp.
Stir-Fried Leafy Greens with Garlic — The greens should stay bright green and crisp, not soggy or watery.
Hot-and-Sour Shredded Potatoes — The potato strips should be evenly cut and remain crisp, with a good balance of sour and spicy flavors.
Tomato and Egg Stir-Fry — The eggs should be soft and tender, while the tomatoes should be juicy, with a good balance of savory, sweet, and tangy flavors.
But these are probably the most common ones. Regional cuisines vary a lot, and every region has its own dishes you’re expected to know how to make well.
