• A chicken egg is a self-contained cooking vessel suited to simple, precise hard cooking.
• The calcium-carbonate shell, cuticle, and two membranes protect the albumen from contamination.
• Fresh eggs peel poorly; aging releases carbon dioxide, raises albumen pH, and weakens membrane adhesion.
• Albumen proteins form the white gel, while the yolk supplies fat, protein, nutrients, and lecithin.

Choosing eggs

• Grade A large eggs are sufficient; a large carton averages 24 ounces, or about 57 grams per egg.
• The carton's Julian packing date identifies eggs aged 20–25 days for easier peeling.
• Side storage for 24 hours before cooking keeps the yolks near the center.
• Washed U.S. eggs require refrigeration because commercial washing removes the protective cuticle.

Steam-cooking, chilling, and peeling

• A folding steamer sits in a large pot above roughly half an inch of rapidly boiling water.
• Refrigerator-cold eggs enter the hot steamer and cook under a lid for 13 minutes.
• Condensing steam transfers latent heat quickly, sets the outer white, and reduces membrane adhesion.
• The eggs chill for about 13 minutes in 3 quarts of cold water, 2 pounds of ice, and pumped circulation.
• One test egg reached about 180–181°F after cooking and 42°F after roughly 12 minutes of chilling.
• Cracking and peeling occur in the cold bath, beginning opposite the air cell with water under the membrane.
• Peeled eggs keep for about seven days in an airtight box between moist paper towels.

Pepper deviled eggs

• The eggs are halved, the yolks removed, the intact whites arranged, and the yolks mashed until lump-free.
• The filling uses green-peppercorn brine, chopped green peppercorns, Dijon mustard, and white pepper.
• Soft butter and mild olive oil produce the creamy emulsion; mayonnaise and strongly flavored oil stay out.
• The cool filling is piped into the whites and finished with pink peppercorns, black pepper, and salt.

MSG and umami

• Robert Ho Man Kwok's 1968 letter linked a post-meal symptom cluster with several possible causes.
• The "Chinese Restaurant Syndrome" heading spread through the press and helped drive "no MSG" signs.
• A later Australian double-blind study found no rigorous evidence linking the syndrome to MSG.
• MSG is generally recognized as safe by the FDA for its specified food uses.
• Protein-bound glutamate has little direct taste, while free glutamate activates savory umami receptors.
• Kikunae Ikeda isolated glutamic acid from kombu and named its savory taste umami.
• Modern MSG production ferments carbohydrates with organisms such as Corynebacterium glutamicum.

Egg salad

• Damaged but edible peeled eggs become egg salad rather than waste.
• The yolks are mashed with mayonnaise, Dijon, salt, onion powder, white pepper, and MSG.
• The whites are coarsely chopped, folded into the yolks, and chilled for 30–60 minutes.
• Japanese-style milk bread provides the final sandwich format.
