Vital Farms Pasture-Raised Eggs (line)

A versatile choice for breakfast, baking, and everyday cooking, with pasture-raised sourcing I prefer.

Not for: Vegans or anyone with an egg allergy.

Which one fits you

raw or runny eggs for pregnant, elderly or immunocompromised eaters

Davidson's Safest Choice Pasteurized Eggs (line)

These eggs are pasteurized in the shell, so you can use them in raw or lightly cooked dishes with much lower salmonella risk.

Not for: People who whip whites to stiff peaks often, because in-shell pasteurization slows foaming.

Check before you buy

Housing claim backed by a certifier. Under Certified Humane, 'pasture-raised' means 108 sq ft of outdoor space per hen with rotation, and 'free range' means 2 sq ft. Look for the certifier's seal, not just the word on the carton. Unaudited terms like 'cage-free', 'farm fresh' or 'natural' guarantee little or nothing about outdoor access.
Pack date. Read the three-digit Julian pack date (001 to 365) on USDA-graded cartons, not only the sell-by date. The pack date tells you how fresh the eggs really are, which matters for poaching and whipping.
Grade. Choose Grade AA for poaching and frying. Grade A is fine for baking and scrambling. Higher grades have firmer whites and taller yolks, which hold their shape in the pan.
Cold chain. Keep eggs refrigerated at 40°F (4°C) or below from delivery onward. US eggs are washed, which removes the protective cuticle, so they must stay cold.
Format matches the use. Use shell eggs for general cooking, cartoned or powdered whites for high-protein or meringue use, and plant-based substitutes only for egg-free diets. Each format performs differently when it comes to binding, foaming and scrambling.

Questions

Are brown eggs healthier than white?

No. Shell color comes from the hen's breed. Nutrition depends on diet and freshness.

Do I have to refrigerate eggs?

In the US, yes. Commercial washing removes the natural coating, so keep them cold.
