Types of Udon Noodles
There are several types of udon noodles, each varying in texture, thickness, and preparation style. Here are the main types:
1. Fresh Udon
Thick, chewy, soft noodles are often sold in vacuum-sealed or frozen packs. These are ideal for stir-fries and soups.
2. Frozen Udon
It is similar to fresh udon but firmer and retains a better chewy texture when cooked. This is preferred for stir-fried dishes.
3. Dried Udon
Thinner and less chewy than fresh or frozen udon. It needs longer boiling and is commonly used in soups.
4. Pre-cooked (Instant) Udon
It comes in vacuum-sealed packs, ready to heat and serve. This is great for quick meals but softer in texture.
5. Whole Wheat Udon
It is a healthier alternative with a nuttier flavor and firmer bite and is often used in nutritious meals.
6. Sanuki Udon
This specialty is from Kagawa, Japan, known for its extra chewy and firm texture and is ideal for hot and cold dishes.

Instructions to make stir-fried chili garlic noodles:-

Note: The cooking time will vary depending on the type of udon noodles you use.
Prepare the sauce:
Add toasted sesame oil, soy sauce (light and dark), vegan oyster sauce, chili sauce, and mirin (rice vinegar) in a bowl. Add a teaspoon of cornstarch and prepare a mixture.
Stir fry the veggies and noodles:
Heat oil in a wok. Add minced garlic and chili flakes. Saute for 15-20 secs until it becomes fragrant. Don't overcook it to burn it. Remove once done.
Add more oil to the wok. Add veggies, sliced onions, green onions, garlic, and ginger. Saute for 3 - 5 minutes until the veggies wilt. Avoid overcooking, as the veggies will lose their crunch and become softer.
