Normally, new husbands appreciate their wife's cooking no matter how it tastes, out of respect for her effort and feelings. They only difference here is that instead of the food being too salty or not salty enough, it's just too spicy. He did literally mean it when he said he was responsible for her happiness, so seeing her smile and be cheerful made him indulge her in her little prank.
