The Chemistry of Caramelisation on the BBQ (And How Your Rub Makes It Happen)

Why your meat turns golden, glossy and irresistible — and how your rub makes it happen.

Caramelisation is the moment your BBQ goes from “pretty good” to “holy hell, look at that colour”.
It’s the glossy sheen on pork belly.
The sticky edges on chicken wings.
The deep mahogany glow on ribs.
The sweet‑smoky crust that makes people hover around the grill like seagulls at the beach.

But caramelisation isn’t luck.
It’s chemistry.
And your rub — especially balanced blends like
Fixes Most Things — is the catalyst.

Let’s break down exactly what caramelisation is, how it works on the BBQ and how to make it happen every single time.

🔥 1. What Is Caramelisation?

Caramelisation is the chemical reaction that happens when sugars hit heat.

At around 160–180°C, sugars begin to:

  • Break down
  • Darken
  • Thicken
  • Sweeten
  • Stick
  • Gloss

This creates:

  • Colour
  • Shine
  • Sweet‑smoky depth
  • The iconic BBQ crust

It’s the flavour equivalent of turning the saturation up on your food.

🔥 2. Why Caramelisation Loves the BBQ

The BBQ is the perfect caramelisation machine because it gives you:

  • Direct heat
  • Dry heat
  • High heat
  • Smoke
  • Fat rendering
  • Airflow

All of these accelerate the caramelisation reaction.

This is why BBQ colour hits differently compared to oven cooking — the environment is built for it.

🔥 3. Sugars Are the Fuel

Caramelisation can’t happen without sugar.

Fixes Most Things uses:

  • Brown sugar → deep, molasses‑rich caramel
  • White sugar → fast colour and shine

Together, they create:

  • Early colour
  • Slow burn
  • Balanced sweetness
  • Sticky bark

It’s engineered caramelisation — and the same logic applies to blends like
Sweet Heat & Shenanigans,
which is built for deep, glossy colour.

🔥 4. Salt Supercharges Caramelisation

Salt doesn’t caramelise — but it helps caramelisation happen.

Salt:

  • Pulls moisture to the surface
  • Dissolves the rub
  • Creates a sticky layer
  • Helps sugars melt evenly

Lake Deborah salt is especially good at this because it’s clean and mineral, not harsh.

🔥 5. Heat Controls the Reaction

Caramelisation is heat‑dependent.

Below 150°C:
Sugars melt but don’t caramelise. Colour stays pale.

160–180°C:
Perfect caramelisation zone. Glossy, golden, sticky magic.

200°C+:
Caramelisation speeds up. Risk of burning increases.

This is why Australian BBQ — which runs hotter — needs balanced sugars, not sugar bombs.
Fixes Most Things is built for this exact environment.

🔥 6. Fat Helps Everything

Fat is a caramelisation accelerator.

As fat renders, it:

  • Mixes with sugars
  • Helps them spread
  • Creates shine
  • Prevents burning
  • Adds flavour

This is why:

  • Chicken thighs
  • Pork belly
  • Ribs
  • Salmon

…all caramelise beautifully.

🔥 7. Smoke + Caramelisation = Deep Colour

Smoke particles bond to caramelising sugars.

This creates:

  • Darker colour
  • Deeper flavour
  • More complex bark

It’s why smoked meats look richer than grilled meats.
Fixes Most Things is engineered to interact with smoke in all the right ways — and herb‑forward blends like
Herbalicious Rubdown
and citrus‑sparked blends like
Zesty Slap
take on smoke differently but beautifully.

🔥 8. Moisture Is the Enemy

Caramelisation can’t happen until the surface dries.

Wet meat = steaming
Dry meat = browning

This is why:

  • Patting meat dry
  • Letting the rub sit
  • Avoiding overcrowding

…are essential steps.

🔥 9. Why Some BBQ Turns Black (Not Caramelised)

Blackening happens when:

  • Heat is too high
  • Sugars burn
  • Meat is too wet
  • Rubs are unbalanced
  • Fire flares up

Fixes Most Things avoids this because:

  • Balanced sugars
  • Clean salt
  • No fillers
  • No artificial sweeteners
  • No heavy smoke powders

It’s built for caramelisation, not combustion.
