In a microwave safe bowl, melt remaining 5 oz chocolate in microwave for 45 seconds. Stir and continue to microwave in 15 second intervals, stirring after each, until melted. Carefully holding each macaroon upside down by its base, dip peaks into chocolate. Place on a parchment lined baking sheet in the refrigerator until chocolate is set, about 30 minutes. Then store in an airtight container in refrigerator for up to 3 days.
