If you're an avid baker, you're probably familiar with the art of separating eggs, and you'll know that many recipes call for just the yolks (like custard, mayonnaise and lemon curd).
To prevent throwing any good food out, it's worthwhile having a few go-to recipes on hand to use up your leftover egg whites.
How to store them
Any leftover egg white should be put in airtight containers and stored in the refrigerator immediately. They can be refrigerated for up to two days.
If you won't have a chance to use your egg whites straight away, you can freeze them for up to three months. A handy tip is to pop them into individual ice cube trays so you can use as much at you need at the time. You can also store them in freezer bags, but be sure to label them carefully so you know how many you've got to bake with.
Keep in mind, though, once they're defrosted, they are not safe to re-freeze. You should defrost in the fridge overnight the day before you need them.
Angel food cakes
Angel food cakes are beautifully light, sweet desserts that contain no fat or butter. Their fluffiness comes from incorporating air into egg whites and an unusual cooking method where the cake is inverted.
They are often accompanied with light toppings such as fresh berries and a sweet syrup. Nothing too heavy should be placed on top as it could damage the cake. Similarly, any rich toppings would affect the beautiful lightness of the angel food cake.
When it comes to cocktails, egg white is a brilliant addition when wanting to add a bit of extra texture to your cocktail. They create a silky beverage that feels rich on the tongue, as well as adding an attractive frothy top (like a cappuccino).
Pisco and whiskey sours and some of the more common drinks you can expect to add a dash of raw egg white to, but you'll also see classic cocktails called 'fizzes' with this secret ingredient.
Cocktails that contain egg whites generally require more shaking than normal drinks as you need to ensure the whites form their frothy structure (just like whisking meringues!).
This retro treat, which is served as little cubes of sugary-coconutty goodness, relies on egg whites as the binding agent.
It's generally served with a dash of food colouring to create it's pastel pink appearance, making the perfect edible gifts for special occasions. Keep in mind, though, as the egg whites aren't cooked - you'll want to store it in the fridge (if it lasts that long!)
Many traditional cakes will call for fluffy icing in their recipes as the perfect way to decorate the dessert with a smooth, marshmallow consistency.
The addition of a few drops of colouring will tint this frosting to any hue of your liking. Make sure to frost the cake around the base near the board; this forms a seal and helps keep the cake fresh.
Macaroons and macarons
It's the age-old question that leaves even the most experienced bakers checking themselves... Is it a macaron, or a macaroon? Nope, they're not actually the same thing - but they do have one key factor in common: they're both based on egg whites.
The French macaron will probably be more recognisable to you. It almost looks like a cookie sandwich, consisting of a crunchy, fluffy meringue and almond 'buns' which surround a buttercream, ganache, jam or fruit curd centre.
Macaroons, however, are little coconut biscuits made from egg whites, condensed milk, sugar, and dried coconut, often piped with a star-shaped tip. Macaroons are often topped with almonds, glace fruits or dipped in chocolate to create an indulgent mid-morning treat.
Ah, meringues... There's nothing better than biting into a sweet, crunchy homemade meringue and letting the sugar dissolve on your tongue. They can be served soft or hard, depending on how you want to use them, but one thing they all need: egg whites.
Whisking clean egg whites will give you that beautifully fluffy texture you see atop lemon meringue pies. It's important not to over-whisk them before you add the sugar, though, as the foam will break down.
And while you wouldn't top your pies or tarts with crunchy meringue, it goes beautifully in a homemade pavlova.
There's just something irresistible about a light, creamy chocolate mousse; it's truly the best way to finish up a heavy meal.
The essential base ingredient of every mousse is egg whites to create that distinctly fluffy texture. And with these delicious recipes you'll always have a great way to use up leftover egg whites.
This classic egg dish is extremely versatile and can be gobbled up for breakfast, lunch or dinner. Simply whisk up some eggs, fry up some onions, mushies and bacon, and you're good to go.
Omelettes made with just egg whites, rather than the whole egg, have risen to popularity in the past few years as there is a growing focus on low-calorie, low-fat meals. The egg whites contain most of the protein and amino acids, without the fats which are sourced in the yolks. They'll also give you a 'fluffier' omelette, if whisked beforehand.
The best part? You can fill your egg white omelettes with whatever you heart desires, with everything from sweet stewed fruits to savoury bacon and ricotta.
