M, L and XL eggs: which size should you choose?

In brief. M, L and XL primarily classify eggs by weight. They support recipe consistency but do not prove better taste, nutrition or a particular housing system.

What the letters mean

Under the European regulation often used as an international reference, M is at least 53 g and under 63 g, L is at least 63 g and under 73 g, and XL is 73 g or more. A buyer in Morocco should still check the locally applicable specification and the supplier’s declared weight. A letter without a verifiable range is incomplete information.

When size changes a recipe

For a fried egg or simple omelette, unit count mainly sets the portion. In baking, the total water, protein and fat delivered by the eggs can change emulsion, structure and moisture. Replacing four M eggs with four XL eggs adds meaningful mass. A professional solution is to state the required egg weight without shell.

Choose for the intended use

M works when a daily recipe has been tested for that format. L gives a larger unit and may simplify some recipe cards. XL creates a prominent egg-led plate, but price and availability need comparison with actual yield. The best size is the one that reproduces the intended portion with the least variation.

Calculate useful cost

Price per egg alone is a weak purchasing metric. Compare price per usable kilogram, breakage, consistency, labour and leftovers. A more expensive pack may be sensible if it avoids using a second egg per plate. The opposite may be true when the recipe is already controlled by weight.

Test before changing the menu

Prepare the same dish with each available size, weigh what is used and photograph portions under the same conditions. Record cooking and texture. A test across several services is more informative than a visual preference. Put the final size or mass in the recipe card and purchasing specification.

Use a repeatable method before relying on a tip

In a home or professional kitchen, reliable results start with a short record: number of eggs, stated size, starting temperature, vessel size, cooking time and intended result. Change one factor at a time. This prevents a difference caused by the oven, pan, storage or quantity from being wrongly attributed to the egg.

Size is a weight class, not a promise about taste, nutrition or housing. A recipe should state whether it depends on egg count or egg mass. For professional batches, weighing beaten egg can be more repeatable than counting units when available sizes change.

Document the result for the next service

After a trial, record what was actually prepared and served: batch quantity, portions sold, station time, texture variation, breakage and leftovers. Keep the relevant lot and size reference with the record, but do not turn one observation into a general claim about a product. Three comparable services create a stronger basis than one successful plate.

Date each new recipe version and communicate it to both purchasing and kitchen staff. If the planned size or pack is unavailable, approve the substitution before production. Record whether the recipe is adjusted by count or weight and who authorised the change. This prevents each shift from making a different correction.

Review the result against the original objective: consistent portion, safe cooking, service time, cost and waste. Improvement can involve a smaller batch, different vessel, clearer storage position or a delivery change rather than a different egg. Assign the action and a review date so the note becomes a decision, not an archive.

Keep purchasing and receiving aligned

The purchase specification states range, size, pack, quantity, city and frequency. At receiving, staff compare quantity, shell condition, lot and the agreed product before storage. A substitution is not accepted silently because it can change recipe mass and cost. The lot record stays with the eggs after the outer case is opened, supporting both stock rotation and a precise response to a complaint.

Practical checklist

• Check the stated weight range
• Weigh shell-free egg for baking
• Compare cost per finished portion
• Test before changing size
• Do not turn size into a quality claim

The food-safety foundation

A clean, uncracked shell can still contain bacteria. Wash hands, clean equipment and keep raw egg away from ready-to-eat food. FDA guidance advises cooking eggs until white and yolk are firm and egg dishes to 71°C. A recipe served raw or lightly cooked should use an appropriate pasteurised egg or egg product.

Serve cooked dishes promptly or hold them under a validated safe-temperature procedure. FDA guidance says not to leave cooked eggs or egg dishes at room temperature for more than two hours, or one hour above 32°C. These international references do not replace Moroccan requirements or a restaurant’s own food-safety plan.
