I think that if it upsets your wife, you should not eat until she serves it. You may be making her anxious because she may feel that she won’t have enough food. Maybe you can compromise and she can give you some food to taste??
Also, the man may be the king of the house, but if the wife is not happy, trust me, no-one will be happy. Try thinking how you would feel if you spent days cooking and your wife wanted to eat before Yom Tov.
