Step 1Place the apples in a large glass container and cover with the sherry. (Keep the sherry bottle; you will strain the infusion back into it once ready.) Cover and place the jar in the refrigerator for 5 days.
Step 2Each day, pick up the jar and gently agitate, turning it upside down a couple of times so that the sherry circulates around the apples. On the fifth day, strain the sherry though a fine strainer and funnel it back into the sherry bottle. Store in the refrigerator until ready to use.
