“sparingly” は「控え目に」という意味です。“hate” という言葉は、拒絶するような意味が強いので、控え目に使いましょう。日本語の「嫌い」程度の感覚なら、“do not like” をお勧めします。

作文について、一般的なことですが、難しく書こうとしない方がいいです。少ない語数で明瞭に伝えられるのが一番。

Keep in mind:

(1) Write one simple sentence. Add some words to it. Replace some words with new words. Being playful is the key to learning any new skill.

(2) It will take years of practice to write well in any language. If it is not your native language, it will take even longer.

(3) There is no perfect writing. You just keep practicing to become more proficient in writing, just like any other skills.

Thank you so much for teaching me politely. I would like to write difficulty or complicatedly but I still can't. I must improve it, too. I don't have enough vocabulary and I don't understand how to use difficult words correctly. I hope these practices helped me.
I have questions. I don't know the different in meaning between it depends and it depends on. Also, what does "sparingly" mean?

I see that you prefer a casual writing style that goes well with social media. So I would like to keep it that way. Every person writes differently, so my writing is just one example.

I’ve tried British food in England. I like English breakfast, fish and chips, pies, and pastries that my host mother prepared. I would like to choose items for my English breakfast. I would pick fried eggs, beans, bacon, and bread. That would be it. I would have a tasty English breakfast, but I know that my choices might not be so tasty in other places. I visited restaurants in England, and I did not like their dishes. They had quite strong tastes. They were more salty and spicy than my host mother’s dishes. They were even worse when I saw the expensive bills. I felt like I was wasting my money. Good bye, my money.... lol. Other than that, I always enjoyed eating them.

Recently, bloody hot in Japan.

Notes:
1. You bake pies and pastries. You make fish and chips. You don’t cook them. So I chose the word “prepare” to cover all the foods listed here.

2. If you are “picking up” something, you are lifting it. In this case, I think you mean “choose” or “select,” so I removed “up.”

3. I replaced “suppose” with “know” because you clearly understand the taste differences. You verified them from your own experience. It’s not like viewing Earth from space.

4. You can use “it depends” without “on.” If you say “it depends on,” you will have to say what it depends on, or you will be asked, "Depends on what?" In this case, however, I think the word “depend” makes your sentence vague, so I rephrased it.

5. You might want to use the word “hate” sparingly, even though many people (especially kids) use it all the time. As an adult, you would not sound very mature or thoughtful if you used it often. I recommend that you use “do not like” and reserve “hate” for something truly hateful (e.g., I hate violent crimes).

6. I added “than my host mother’s dishes” just to add more clarity.

7. You can also write “I felt as if” instead of “I felt like,” but again, I want to keep your casual style.

8. Losing money means paying for nothing. You got the foods, but you think you could have spent your money for something else. In this case, “wasting money” would be more appropriate.

9. The social media acronym, “lol,” is used between friends and families. It’s up to you if you want to keep it here.

10. The last sentence is hard to understand. “Anyway” seems abrupt here, and it does not lead nicely to the words that follow. “Almost enjoyed” means that you did not enjoy it. Is that what you mean? If so, you might want to write, “So I could not fully enjoy eating them.” On the other hand, if you mean that you mostly enjoyed eating them, you could use my example above.

Let me know if you have any questions.
