Notes
This cherry meringue dessert will keep well in the fridge for 2 to 3 days stored in a cool dry area. It should be lightly covered with plastic wrap or foil. To keep the meringue from getting soggy, try not to cover it too tightly – you want a little air circulation.This recipe does not freeze well since the meringue texture changes when frozen and thawed.We recommend that the meringue mixture not be topped with the cherry mixture until serving.
