Is Udon Healthier than Ramen?
Udon noodles are thick, pale, wheat flour noodles often used in hot noodle soups. Ramen noodles are much thinner, yellow wheat noodles that are also used in soups, usually flavored with soy or miso.
As to which is healthier, it really depends on the preparation. Fresh udon noodle soup made at home will likely be healthier than store-bought ramen that's packed with sodium and processed ingredients.
However, a homemade ramen dish where you know exactly what's going into the recipe would be healthier than the store version. It really depends on the additions you make and how you cook them.

What is Dashi Broth Made Of?
Dashi broth is a Japanese broth used widely in soup recipes - for example, to make udon broth. Dashi is made from a combination of water, dried kelp, bonito fish flakes, dried anchovies and shiitake mushrooms. Most dashi broths will use water and two of the above ingredients. Dashi is a great base for noodle dishes and has that coveted umami flavor. It is also great in Agedashi Tofu, a Japanese favorite.

To cook udon noodles, you will need to bring water to the boil and place the noodles in the water until submerged. Cook until they are tender but not too soft and slippery. The cooking time may vary depending on whether you are using semi-dried, dried noodles, or frozen udon. I prefer frozen udon noodles, which take 1 minute to cook.
