JREFへようこそ! (welcome to JREF!)
Actually when writing a recipe you generally don't use てください form (you can use it for the last "please enjoy"). Either plain verbs or sometimes polite (ます) form normally. Your conjugations are right, though.
I think you have a few problems relating mostly to your dictionary. You must be careful when looking up new words in Japanese - don't just put in English and take the first word that comes out, check example sentences to make sure you have the right sense of the word.
"ryorihou" → レシピ
ソースパン → 鍋 (nabe)
さしいれる → just use いれる
テイクアウト is for "take out" like "take away" food. For draining pasta, you can use お湯を切る (oyu wo kiru), also ざるをあげる
とりまぜる → just use まぜる
