Presented here for study, not as a practical ruling. The Shulchan Aruch rules by Sephardi custom, the Rema's glosses by Ashkenazi custom, and the Kitzur follows Ashkenazi custom. For a practical question, ask your rabbi.
א הַמַּדִּיר אֶת אִשְׁתּוֹ מִלֵּהָנוֹת לוֹ, אוֹ שֶׁלֹּא תִּטְעֹם אֶחָד מִכָּל הַמִּינִים, אוֹ שֶׁנָּדְרָה הִיא וְקִיֵּם לָהּ הוּא, עַיֵּן בְּיוֹרֶה דֵעָה בְּסִימָן רל"ה סָעִיף ג':
1 One who vows [neder] against his wife from getting benefit from him, or that she cannot have the taste of a certain type [of food], or she made that vow and he upholds it [and doesn't void it], see Yoreh Deah Siman 235:3.
