Flan is a custard dessert with a soft, smooth texture and a caramel topping. It can be made in different ways, but typically contains eggs, milk, sugar, and vanilla extract.
While some recipes for flan do call for raw eggs, most use cooked eggs instead. This is because raw eggs can pose a risk of food poisoning if they are not cooked properly. Cooking the eggs helps to kill any bacteria that may be present in the raw egg and makes the flan safer to eat.
If you are concerned about using raw eggs in your flan, you can always opt for a recipe that uses cooked eggs instead. Or, you could try using pasteurized eggs which have been treated to kill bacteria before they are sold. Pasteurized eggs can usually be found in the grocery store near the regular egg section.
