What is it?
- Simply a mixture of all-purpose flour, baking powder, and salt
- Commonly used throughout the Southern US, as well as other countries
- It's not meant to replace yeast or plain flour -> In fact, it is recommended to not combine with any other "leavening agent"
- Common for "quick-rise" items (biscuits, pancakes, cupcakes, etc.)
- You can read more about its use and history here or here
How to make / substitute
- 1 Cup All Purpose Flour
- 1.5 tsp Baking Powder
- 0.25 tsp fine salt
- Mix together as evenly as possible - whisking will help
- Ratio should be 2:1 for self-rising flour : brown sugar
- 1 (US) Stick of Butter = 8 Tbsp.
- 1 Cup (All Purpose) Flour = 120-130 grams
- 1 US Tbsp = 3 US Tsp
Pick the ripe cherries
- (best when red and have slight softness to them. Brown and squishy is past ripe).
Separate the bean from the pulp / meat
- You can use a knife
You need to soak the bean to remove the residue from the pulp (slimy layer)
- Leave in water for 24-48 hours
- Occasionally check if the beans are ready by taking some beans, and gently hand washing - if they look clean and feel "gritty" - not slippery / slimy - then the "mucilage" layer around the parchment layer has broken down and fermented / dissolved off.
Dry the bean / parchment layer
- Sun drying is recommended, but other methods can be used that are far quicker
- In general, the temp needs to be kept low (around 100 F) during drying
- Moisture content needs to drop under 12%, ideally 11%
- The parchment layer should feel dry, light, and flaky when this is done
Separate / remove the parchment layer
- Can be done by hand, tumbled, etc.
Many different methods, and lots of guides out there
In general, you can do it by sight (the beans change color quickly, as well as expand and pop), and you just want to keep the beans moving while roasting
- Many roasters stop right after the first crack (city roast) or near or start of, but not after 2nd crack (near french roast)
- Popcorn air-popper or stove-top popper: both keep the beans moving!
- Standard cooking pot: stir beans while roasting
