Too much heat scrambles the egg, so keep it below a simmer and keep stirring. The egg is only lightly cooked; for pregnant, very young, elderly or immune-compromised eaters, use the condensed milk version.
Any tips from this recipe?
Use a firm, plain biscuit. Rich or soft biscuits go to mush when the warm chocolate hits them. For a nut-free slice, replace the walnuts with more biscuit or with sultanas.
