Soft-Ball Test: If you don’t have a thermometer, drop a small amount of syrup into ice water. If it forms a soft ball, it’s ready. Ensure it boils for at least 5-7 minutes for a stable fluff.
Use a Candy Thermometer: This ensures precise results for the sugar syrup. You’ll want it to read Soft-ball stage or 240° F

- 1 tsp cream of tartar
- 1/3 cup water
- 3/4 cup light corn syrup

If you’re not sure, give it another minute or two. More time is better than less.
- Once the egg whites create thick peaks, carefully pour the syrup in a thin, steady stream into the whites with the mixer is on medium-low speed. Let it mix fully in between pours.

Can this fluff be made into chocolate covered marshmallow cream?
I have never done that but you can try!
I see 2 references about storage. The first says that the fluff can let 1 week at room temp and in another section of the text, it says can last 6 weeks. Can you clarify for me?
Thanks
