Cappeln Apple-Butter Cook September 9, 1995. By noon, eight brass and copper kettles bubble along at St. John's UCC Church. There were 14 kettles at 7:00 a.m. when 41 bushels of Jonathan apples, cut up the previous day, were put on the fire to begin the all-day cook. Water from the white buckets is added if the butter becomes too thick. -
