接続詞の使い方

This was a successful dish. I made it a little more than a week ago. Since I've been busy showing you signs with mistakes, I didn't post it on the blog.

I was talking with someone last week. She told me about Thai curry in Thailand and the same dish at a Thai restaurant in Japan. She told me:

× It was good but not the one we ate in Thailand.
○ It was good, but not as good as the one we ate in Thailand.
○ It was good, but it wasn't as good as the one we ate in Thailand.

I feel the first sentence has a mistake because the two things connected by the conjunction aren't the same type of thing: "good" is an adjective, but "the one" is a pronoun.

In the second sentence, we just connect "good" with "not as good", both of which are adjectives. In the third sentence, we connect one sentence with another sentence.

This dish in my photo has slices of fried tofu, green pepper (remember this post?), and bean sprouts. <- noun, noun, and noun

I stir-fried everything and added a spicy Chinese sauce. <- verb and verb

Using grammar well is sometimes hard. What do you think about cooking delicious dishes: hard or easy? <- adjective and adjective
