The Right Way to Use Kosmos Q Rubs on Hot Surfaces
How to Use Kosmos Q Rubs on Griddles, Flat Tops & Cast Iron is a common question now that backyard cooks are using Blackstones, Pit Boss griddles, and cast iron skillets more than ever. Kosmos Q rubs are bold, concentrated, and competition-proven—so while they’re incredible on smokers and grills, they also shine on high-heat cooking surfaces when used correctly.

Core Rules for Using Kosmos Q Rubs on Griddles & Cast Iron
Unlike smoking or grilling, griddle cooking is fast, hot, and direct. That means the rules change:
1. Avoid high-sugar rubs at very high heat
Sugary rubs like Killer Bee can caramelize beautifully—but they can also burn if temps climb above 450°F.
2. Use salt-forward or savory rubs as your base
- SPG All Purpose (best overall for hot surfaces)
- Cow Cover
These withstand high heat and give you clean, bold flavor.
3. Apply rub right before or right after searing
On a smoker, you season early so flavor penetrates. On a griddle, seasoning too early risks burning. Use:
- Before sear: SPG, Cow Cover
- After sear: Killer Bee, Spicy Killer Bee
4. Use oil or butter as a binder—not mustard
This keeps rubs stuck to the surface without creating bitterness.
5. Don’t overseason—griddle cooking amplifies salt
Start with 1 teaspoon of rub per pound and adjust upward if needed.
How to Use Kosmos Q Rubs on Smash Burgers
Smash burgers are the #1 use case for Kosmos Q rubs on flat tops. High heat, quick sear, perfect crust.
Best Rubs for Smash Burgers
- SPG
- Cow Cover
- Cow Cover HOT (for heat lovers)
How to Season Smash Burgers
- Form loose 3–4 oz balls of beef.
- Place on a ripping-hot griddle (400–450°F).
- Smash immediately and season with SPG or Cow Cover.
- Flip once a crust forms.
- Finish with a light dusting of Dirty Bird or Killer Bee if desired.
Pro Tip: Add Killer Bee after the flip—not before—to prevent sugar burn.
How to Use Kosmos Q Rubs on Chicken on Flat Tops & Cast Iron
Chicken cooks beautifully on cast iron and flat tops, especially thighs, tenders, and wings.
Best Rubs for Chicken
- Dirty Bird – balanced, perfect for griddle chicken

How to Season Chicken on Hot Surfaces
- Use a small amount of oil as binder.
- Apply Dirty Bird before placing on the griddle.

Avoid: heavy sugar rubs early in the cook—they scorch fast.
Using Kosmos Q Rubs on Pork Chops, Bacon & Sausage
Pork develops incredible crust on a griddle, especially chops, sliced pork steaks, and breakfast meats.

FAQ
Can I use sugar rubs on high heat?

Savory rubs (SPG, Cow Cover) work best before searing. Sweet rubs work best after flipping or finishing.
