Plain flour and buckwheat the same?

No, plain flour and buckwheat are not the same. They are two very different types of flour:

* Plain flour (also called all-purpose flour) is made from wheat and is a staple ingredient in many cuisines. It has a neutral flavor and is versatile for baking, cooking, and thickening sauces.

* Buckwheat flour is made from buckwheat which is actually a pseudocereal (not a true cereal grain) and is gluten-free. It has a slightly nutty flavor and is often used in pancakes, soba noodles, and other gluten-free recipes.

Key differences:

* Grain source: Wheat vs. buckwheat (pseudocereal)

* Gluten content: Plain flour contains gluten, buckwheat flour is gluten-free

* Flavor: Plain flour has a neutral flavor, buckwheat flour has a nutty flavor

* Uses: Plain flour is versatile for many recipes, buckwheat flour is used in specific gluten-free recipes

So, while both are flours, they are quite different in terms of their origin, properties, and culinary applications.
