Two of the best coffee beans in the world to grind up.
Both Hawaiian. Kona Peaberry & Maui Peaberry.
Peaberry , also known as caracoli , is a type of coffee bean.

Normally the fruit of the coffee plant develops as two halves of a bean within a single cherry,

but sometimes only one of the two seeds gets fertilized, so there is nothing to flatten it.

This oval (or pea -shaped) bean is known as peaberry.

Typically around 5% of all coffee beans harvested are of this form.

If you are boiling coffee grounds on a campfire,

crack open a raw egg to sit in the grounds.

That lump turns green taking out the acid.

Some will add a dash of salt to the brew.
