If for some reason you don’t like celery seed, but do like fennel seed, then you could probably add 1 tsp dried Herbs de Provence to this roll recipe in place of the celery seed if desired (and IF you aren’t making a bread stuffing recipe as well for the Thanksgiving Holiday–bread stuffing typically has marjoram & sage already in it and may also have summer savory, basil, and thyme in it as well). Herbs de Provence typically contains basil, fennel seed, lavender, marjoram, rosemary, sage, summer savory and thyme.
If you want to adjust the bread flour content, you could also make this recipe with some whole grain bread flour, substituting up to 1 cup of whole grain bread flour for up to 1 cup of other bread flour in the initial batter dough mixture.
