Why Measuring Eggs by Weight is Essential for Baking
For many baking recipes, precision is key. While some older recipes call for eggs by count, modern or professional recipes specify eggs in grams for a reason. Using eggs by weight removes the variability that comes with size differences. For example, the difference between a large egg (around 57g) and an extra-large egg (around 64g) can alter the moisture balance and structure of delicate baked goods like macarons or cakes. When a recipe calls for a specific weight, such as 80g, a digital kitchen scale is the most reliable tool to ensure consistent and perfect results every time.
The Variability of Egg Sizes
The weight of an egg is not standardized globally and even within the same country, can vary by grade. Understanding these variations is the first step toward mastering precise measurements in the kitchen. For a quick 80g measurement, you might need one extra-large egg and a small fraction of another, or a whole large egg with additional egg content added.
- Medium Egg: Typically weighs 47-54 grams. You would need about 1.5 medium eggs to get 80g.
- Large Egg: A common size weighing 54-61 grams. You will need slightly more than one large egg.
- Extra-Large Egg: Weighs 61-68 grams. One extra-large egg provides most of the required weight, with just a small top-up needed.
Step-by-Step Guide to Weighing Eggs for 80g
For most recipes, you will need to crack the egg and beat it slightly before measuring to ensure a homogenous mix of yolk and white. Here’s how to get exactly 80g using a digital scale:
- Place a clean, empty bowl on your digital kitchen scale and press the 'tare' or 'zero' button to reset the weight to zero. This step is crucial for an accurate reading.
- Crack an egg into the bowl. If you're using large or extra-large eggs, crack one and check the weight. It will likely be close to 80g, but probably not exact.
- Adjust the weight. If you are using a large egg (approx. 57g), you will need to add about 23g more. Crack a second egg into a separate bowl, whisk it, and then slowly add small amounts to your main bowl until you hit exactly 80g. If you're using an extra-large egg (approx. 64g), you only need to add about 16g more.
- Use excess egg for another purpose. Don't throw away the leftover! You can use it for a quick scramble, an egg wash, or save it for another recipe.
This method guarantees your recipe has the exact amount of moisture and binding agent required, leading to superior results, especially in sensitive baked goods like cakes, custards, and macarons.
The Importance of Weighing Yolk vs. White
In some recipes, especially delicate pastries or custards, you may be asked to measure only egg yolks or egg whites. The ratio of yolk to white is not consistent across all eggs, so weighing is even more critical here. A standard large egg white is around 30g, while the yolk is about 18g. Therefore, to get 80g, you would need approximately 4 egg yolks, or just over 2.5 large egg whites.
Comparison Table: Eggs to 80g Conversion
| Egg Size (Approx. Avg. Weight) | Number of Eggs to get 80g (Whole) | Method for Achieving 80g Exactly | 
|---|---|---|
| Medium (approx. 47-54g) | ~1.5 | Crack 1 whole egg plus about half of a second, whisked egg. Use a scale for precision. | 
| Large (approx. 54-61g) | ~1.3 | Crack 1 whole egg and add approximately 20-30g of a second whisked egg until the scale reads 80g. | 
| Extra-Large (approx. 61-68g) | ~1.2 | Crack 1 whole egg and add about 12-20g of a second whisked egg to reach 80g. | 
| 80g of Egg Whites | ~2.5 Large Whites | Crack 3 large eggs, separate the whites, and weigh out 80g. | 
| 80g of Egg Yolks | ~4 Large Yolks | Separate the yolks from 4 large eggs and weigh out 80g. | 
Conclusion: Precision Leads to Perfection
When a recipe requires a specific weight of eggs like 80g, relying on a count alone is a gamble due to the natural variation in egg sizes. From a culinary science perspective, the precise ratio of fat, protein, and water provided by eggs is critical for texture and structure. Investing in a simple digital kitchen scale is the most foolproof way to ensure consistency and prevent recipe failures. By understanding the average weights of different egg grades and using a scale to measure accurately, you can confidently answer the question "how many eggs make 80g?" and achieve perfect results every time.
