Passage: Many historians consider the accession of Henry VII to mark the end of the Wars of the Roses. Others argue that they continued to the end of the fifteenth century, as there were several plots to overthrow Henry and restore Yorkist claimants. Only two years after the Battle of Bosworth, Yorkists rebelled, led by John de la Pole, Earl of Lincoln, who had been named by Richard III as his heir but had been reconciled with Henry after Bosworth. The conspirators produced a pretender, a boy named Lambert Simnel, who resembled the young Edward, Earl of Warwick (son of George of Clarence), the best surviving male claimant of the House of York. The imposture was shaky, because the young earl was still alive and in King Henry's custody and was paraded through London to expose the impersonation. At the Battle of Stoke Field, Henry defeated Lincoln's army. Lincoln died in the battle. Simnel was pardoned for his part in the rebellion and was sent to work in the royal kitchens.

Question: Where did Simnel work after the uprising?
royal kitchens
