Answer: Oh, good question! I don’t do anything to the apple or pear slices I put on boards. Traditional preservatives (like lemon juice, pineapple juice or salt water) interfere with the natural flavor of the fresh fruit, which is intended to pair with the cheeses and other goodies on the board. I usually just put them on the board last. They get eaten so quickly, they don’t have a chance to get that brown. I’ve found that the fruit really doesn’t brown significantly over a few hours and they stay crisp, which is important. I also try to expose as little of the white parts as possible when assembling the board. Hope this helps!
