美味しそうでよだれが出そう！って英語でなんて言うの？

"Drool" is a great verb in English, but be careful when you use it. In my mind, it is often associated with animals, like cats and dogs. If you are joking around with your friends, you can say "I'm drooling!", but if you are with your boss or parents, you may not want to compare yourself to an animal! That's why I thought "mouth-watering" might sound a little politer!

"All The Food You Made Looks Delicious, And It Is Making Me Drool!"

In This Sentence, You Are Complimenting The Person Who Made The Food And You Expressing That It Is Making Your Drool!

"I am starting to drool looking at this food!"

Starting - when you look at the food the drooling begins! Meaning that it looks good And You Are Ready To Eat!

Drool is usually a negative word in English. At best it it neutral. For example, you drool when you sleep. However, people in the hospital drool when they are incapacitated. Babies also drool. You could say "Wipe off that drool."

You are trying to be positive here.

In this case, when you are talking about food, you use the phrase "mouth water". This is similar and refers to your saliva but in a complimentary way. This is a verb. It's an action in both of my answers.

Food can be described as "mouth-watering" when the sight or the thought of it makes you drool.

There is no specific term or way to use 'drool' but you can express how delicious something looks and express it makes you drool by using these:

-I'm drooling just looking at it.
-It looks so delicious, I'm drooling.

when using 'drooling over the food' it doesn't always mean literally over the food, but because of the food looking so good.
using past tense "the food was so delicious I was drooling" used as a past experience about how good the food was.

drool, drooling, drooled.

Drool is when your mouth creates saliva in response to a food stimulus. Often when we are hungry and think of food this happens. You can drool over food and people.
