17dn Butter in apple-like fruit you may pick up (7) ?E???E? 5dn Grain store erected after harvest supports New England people's planting ground (10) ?E?????L?? 20ac Culinary preparation during recall of brand's salad ingredients (8) R??????? RADISHES?
5dn answer is necropolis (NE for New England, crop for harvest + silo (grain store) backwards) = place where people are buried (ie "planted"). 20ac is radishes (dish inside sear (as in burn/brand) backwards). Struggling with 17dn, though.
