麦飯

1. Origins, structure, and basic meaning

• Structure: 麦飯（むぎめし） combines 麦 with 飯, cooked rice or a meal, and here means barley rice.
• Basic usage: It names rice served as part of a meal or rice cooked with barley mixed in.

2. Common pitfalls and similar expressions

• A mixed-grain dish
  • 白米に麦を混ぜて in the second example means mixing barley into white rice. A dish named for an ingredient need not consist solely of that ingredient.
• The verb for cooking rice
  • In 麦飯を炊いた, 炊く is the verb for cooking rice. 焼き魚 in the meal example refers to grilled fish, illustrating a different cooking expression.
