How to say "flour" in Japanese

• 粉こなJLPT N3approx.Common
  nounThe common, general word: it covers flour as its first sense, alongside meal, powder, and dust. This is the word you want for flour in everyday contexts, though the broader meaning means context usually clarifies which substance is meant.
  この小麦こむぎは粉こなにされる。↗

  This wheat is made into flour.
• 打ち粉うちこ
  nounA less common word glossed simply as flour. It is really tied to baking and cooking situations, where flour is dusted onto a surface or dough; for flour as an ingredient in general, 粉 is the ordinary choice.
• プードル
  nounA less common loanword glossed as flour. Note that プードル is far better known as the word for the dog breed 'poodle', so for flour it is seldom the word you want; stick with 粉.

Use 粉 as the ordinary everyday word for flour (and powder generally); 「打ち粉」 and 「プードル」 are less common, specialized alternatives best left until you encounter them in specific cooking contexts.
