Add all of the fish to the bowl with batter and stir to coat. When dropping into the oil, some of the batter will drip off of the fish and that is fine, but if you wait too long to add the battered fish to the hot oil and too much batter drips off, add it back to the bowl before adding to the oil. This is why dropping them one at a time is best. Do this quickly, don't wait for the batter to stop dripping completely before adding to the hot oil. When the fish nuggets are FIRST added to the oil is the most important time to watch them. Don't let them crowd as they will fuse together. After about 10 seconds the batter should be cooked enough that they will not stick together.
