🌈 Why Does Meat Sometimes Look Rainbow-Colored?

🥩 Which Meats Show This Most?

Some meats are more prone to iridescence due to their fiber structure and slicing method:

✅ Roast Beef

Dense muscle fibers, thinly sliced against the grain

✅ Turkey Breast

Smooth, uniform slices reflect light evenly

✅ Ham

Cured and finely cut — ideal for diffraction

✅ Pastrami & Corned Beef

Brined and sliced thin — perfect groove formation

💡 The smoother and thinner the slice, the more vivid the effect.

❌ Debunking the Myths

❌ “The rainbow means it’s coated in plastic”

False — no plastic involved; it’s a light reflection

❌ “Only processed meats do this”

Not true — even fresh cooked steak can show iridescence

❌ “It’s caused by nitrates or dyes”

No — nitrate-cured meats may have a pink hue, but not rainbows

❌ “If it sparkles, it’s bad”

Dangerous myth — many spoiled foods don’t look odd at all
