Cook Hot Curry

　Yesterday, I cooked hot curry for my dinner. Since I used an expensive Japanese Black Wagyu, it became delicious. However, I cooked the curry too much (I made 6 servings), so today's my breakfast and lunch and dinner were also the curry. I think a few percent of now my body is composed of the curry. I'm worried whether my body is giving off a curry smell.

• Yesterday, I cooked hot curry for my dinner.
• Yesterday, I cooked hot curry for my dinner.

  It's implied.

• Since I used an expensive Japanese Black Wagyu, it became delicious.
• Since I used an expensive Japanese Black Wagyu, it became delicious. (You can also say: Since I used an expensive Japanese Black Wagyu, it was so delicious. )

  If you use "was" you may add "so" to intensify the difference between using cheap and expensive curry mix.

• However, I cooked the curry too much (I made 6 servings), so today's my breakfast and lunch and dinner were also the curry.
• However, I cooked too much curry (I made 6 servings), so today's my breakfast, and lunch, and dinner were also the curry.

  I cooked the curry too much means you cooked it for too long.

• I think a few percent of now my body is composed of the curry.
• I think a few percent of now my body is now composed of the curry.

  It sounds more natural this way.

• I'm worried whether my body is giving off a curry smell.
• I'm worried that my body might be giving off a curry smell.

  "Whether" is more often use to compare two situation that are in the sentence. "might" implies the possibility.

Good job! =)
