But if it looks like a science experiment and smells like roast beef?
Go ahead. Make that sandwich. 🥪
🍖 Why Some Meats Show It More Than Others
Deli Roast Beef
Thinly sliced, moist, high in myoglobin (pigment that reflects light)
Ham & Turkey Breast
Smooth, cured surface enhances diffraction
Pastrami & Corned Beef
Spices and brine can amplify the sheen
Raw Fish (like salmon)
Also shows iridescence for the same reason
🚫 Rarely seen in: Ground meat, chicken breast (unless wet), or heavily marinated cuts — because the surface is too rough or uneven.
❤️ Final Thought: Nature Is Full of Hidden Wonders
You don’t need a lab coat to witness magic.
Sometimes, it’s right on your sandwich plate — a flash of green on a slice of turkey, a purple glimmer on roast beef.
That rainbow effect isn’t broken meat.
It’s muscle meets physics — proof that even something as simple as a protein-packed slice can dazzle under the right light.
So next time you see it…
Don’t panic.
Appreciate it.
Because great things — even delicious ones — can be both beautiful and edible. 💛
