I’m a chef and being a chef my work is to taste all the dishes which goes to my guest. It’s being difficult for me to deal with this situation in ramzan. When I say tasting it’s a really serious thing because it’s just not once it’s several time tasting practice what we do in our profession

You can taste as many as you need, provided that you do not swallow any thing.
If you did intentionally, then your fast is void, and you have to offer qaza and kaffarah.
