Poskim write that one who has the minhag of tasting the food for Shabbos before Shabbos is permitted to do so even during the 9 days. Was wondering if this applies only on Friday afternoon, or even if one starts cooking for Shabbos on Thursday night?
When I mentioned this to my wife she thought this halacha was obvious because tasting is not defined as eating. Irrespective of whether that sevara is correct or not elsewhere, it seems to me that it is not the reasoning here. The prohibition of meat and wine does not apply to achilas mitzvah - one is permitted to eat meat/wine at a siyum and for kiddush and havdalah (m'ikar hadin). The tasting of Shabbos food is a bona fide minhag based on 'toame'ha chaim zachu', and hence should be defined as an achilas mitzvah. (Please correct me if you know otherwise.)
