Note from Ricardo
Haskap berries are now available in the frozen fruit aisle of most grocery stores. Bleu & Bon brand is available at IGA. They are also available fresh towards the end of June or beginning of July. The haskap berries can be replaced by the same quantity of blueberries. In this case, add 2 tbsp (30 ml) lemon juice to the compote.
Since the Eton mess contains crunchy meringues that will soften quickly once in contact with the whipped cream, the pie should be eaten as soon as it has been assembled. The pie cannot be refrozen once the toppings have been added.
