have a taste of my cooking.

You can directly reply that since you feel the delicious food I cooked, you should come and taste my cooking together. When others say that your cooking is delicious, it shows that you are very interested in your cooking. At this moment, you should take the initiative to invite others to taste your own cooking. Only in this way can the relationship between friends be deeper and you can take the initiative to help each other when you encounter difficulties in life.
