Gooey meringues

Preheat oven to 150 ºC.
Place egg whites in a large bowl (if you’re using a hand-held electric whisk) or the bowl of your food processor. Whisk on low for 2 minutes, or until whites are foamy. Whisk on medium for 1 minute, then on high until whites form stiff peaks.
Whisk in sugar, a little at a time, on high speed. Add colouring and whisk until mixture is stiff and glossy.
Drop 8 large or 16 small spoonfuls of mixture onto a greased baking sheet. Using the back of a spoon, lift mixture to make peaks.
Place in oven and reduce heat to 140 ºC. Bake for 30 minutes. Turn oven off and leave meringues to dry out for at least 4 hours, or overnight.
Dust with icing sugar and store in an airtight plastic container.
