Can Blood Be Used As A Substitute For Eggs
One medium egg can be substituted with 65g of blood, and an egg white with 43g of blood. (Or, to put it another way, a single porker may replace three to six dozen eggs since a killed pig provides between 2.25kg and 4.5kg of blood. Cooking with blood is somewhat analogous to cooking with eggs.
Although I am intrigued by the idea of using blood in place of eggs, scientifically and culturally, they are both essential for baking. The concept of using blood as a substitute for eggs intrigues me from a scientific and cultural standpoint, both are essential foci for Nordic food labs. The Nordic Food Lab has taken this idea one step further, testing whether coagulated qualities from blood could be used in baking the way that eggs are. The Nordic Food Lab found animal blood to be a viable egg substitute for a wide range of dishes, including ice cream.

Using blood in meat products is not a new idea, but Nordic Food Lab took the idea one step further by seeing if the bloods coagulating properties can help perform the same role eggs play in baked goods. Bloods coagulating properties led us to focus on blood as a replacement for eggs in sweet products, since egg intolerance is one of the main food allergies that affect children in Europe. The European food tradition of using animal blood has a long history, however, has fallen by the wayside. Because the Nordic Food Lab is interested in (re)valuing the obnoxious and forgotten, we had to look a bit deeper at bloods definition as well as how to handle it properly, and because egg allergies are one of the most common food allergies in children in Europe, we turned to blood because of its coagulating properties as an egg replacement. It has somehow become controversial, nearly banned; however, it has been used as food as long as animals were killed and eaten.
In researching for this piece, I learned it is used in not-so-obvious things, such as candy and wine, and so have spent the past couple of weeks continually worrying about accidentally eating animal blood. It is easily one of the more traumatizing food experiences I have had, but honestly, I found it to be far less horrifying than eating anything made with animal blood. Blood also works well as an egg substitute in almost any recipe, but there is at least one downside.

In theory, you could use liquid from cooked home-cooked chickpeas, as well, but they might be too liquidy to be used as egg replacements. Chickpea liquid is the most common form of aquafaba used as an egg white substitute, as it has a neutral flavor and low insoluble fiber content, giving it a suitable consistency for making gels and meringue.
To use aquafaba as an egg white substitute in standard baked goods or in flavor-forward recipes, just measure the desired quantity and whisk it together until foamy. To make egg white substitute with flaxseed, combine ground flaxseed with hot water, vigorously stir, and let rest at least 5 minutes. To duplicate the fluffiness of egg whites, you will need to use ground chia seeds or chia flour. Once you get your texture down to more gel-like consistency, stir in 1/2 teaspoon of baking powder for each egg mentioned in the recipe.

Chef In You suggests mixing 1 tablespoon of each vinegar and water, and then adding 1 teaspoon of baking powder for every egg, but use this substitution only for recipes calling for multiple eggs, such as cakes.
I use about 1/3 of a cup of buttermilk or yogurt for every egg, though some chefs recommend using 1/2 a cup. Sometimes eggs are also used purely for moisture, in which case 1/4 cup water, milk, plant milk, juice, or fruit puree may substitute for one egg. In desserts, baked goods, and pastries, a variety of fruit varieties can be used for the same purposes that eggs do. Chickpea flour can be used in many recipes to provide both the texture and color that eggs otherwise would, and also the nutritional benefits including protein, folate, iron, calcium, and several other vitamins and minerals.
In fact, egg and blood have a very similar protein profile, particularly in terms of albumin, and given that they are both, for instance, an egg white could be replaced by 65g of blood, or 43g of blood could replace an egg yolk (about 33g). The protein composition of blood is very close to egg, so they both coagulate similarly. In fact, eggs and blood exhibit similar protein compositions, especially albmin, which gives both of them clotting properties. The protein ovalbumin makes up roughly 54% of egg-white proteins; conveniently, related albumin makes up roughly 55% of proteins in blood plasma.
Hemoglobin, an iron-binding protein responsible for blood cells red colour, is found primarily in red cells, though there are white cells and platelets within the serum and platelets.
A similar protein composition may be used in making deserts like ice-cream, meringue, sourdough bread, pancakes, and cakes, which all have the aftertaste of blood. Using this technique, we developed recipes for bloody sourdough pancakes, bloody ice-cream, bloody meringues, and bloody chocolate sponge cake. Blood ice cream, chocolate cupcakes, sourdough-blood pancakes, and blood sugar meringue were created using this approach.
You may not be seeing blood cream on one of our ice cream carts any time soon, but using blood in foods makes a lot more sense right now. Despite the blood being a brutal fact of life, animals were slaughtered in order to put food on the plate in front of us, one of the best food teams in the world is calling for blood to be used more extensively in everyday foods that we eat.

The lab has had success in replacing eggs with blood in cakes, meringue, pancakes, and ice cream, among other sweet dishes. Blood as an egg replacement in meringues seemed tricky from a texture perspective initially, but after whipping the blood and sugar into that glorious froth, any misgivings were erased.
Follow along to the 1994 dissertation from Iowa State University, where researchers compared the baking of egg whites with the plasma of cows blood, finding the egg-white cakes boasted a slightly larger volume, significantly higher crown profiles, and finer consistency than the plasma versions. The blood cookies came out of the oven approximately one-eighth of an inch shorter than a control batch. If you are interested in giving this idea a shot, and have a butcher with plenty of meat around, this amounts to 2.3 ounces/65 grams of blood per egg, 1.5 ounces/43 grams per egg white.
Can drinking blood hydrate you?
Around 9g of salt are included in one litre of human blood. Three and a half times your recommended daily allowance (RDA) would be provided by the three litres you drink each day, which may lead to renal failure and dehydration if you didn’t also drink water, or hypertension if you do.
Where does blood go if you swallow it?
You may feel ill in your stomach after ingesting blood. You could feel queasy from vomiting. Eating cold, a soft meals for a few days after a mouth bleed is recommended to help your mouth recover. Food that is too dense or sticky may cause the bleeding to resume.
How much blood equals to an egg?
Eggs and blood have similar protein compositions, according to Organic Authority. One unique characteristic in particular is albumin, which is responsible for both coagulation and flocculation properties. Formally, the egg-to-blood ratio used in cooking is as follows: one egg equals to 65g of blood.
