Sponge Candy Will Not Stay Fluffy

My Sponge Candy will not stay fluffy, just settles down and gets hard. Please help!!!

I used 1 cup regular sugar, 4 tbsp of light corn syrup, and 2 tsp of baking soda sifted into 1 tbsp of water.

I heated up the sugar and syrup slowly to a boil, then let it cook for about ten minutes until it was a light brown color. I put in the soda and it puffed up and all, but then when I poured it into my pyrex Pam-sprayed pan, it stayed up then slumped and was barely aerated.

It still tasted good but it is extra hard and different then the normal kind. I have tried many times and failed miserably, please help!

Thank you.

I haven't made this particular type of sponge candy myself, but there are some other folks who have been discussing making Sponge Candy and Angel Food Candy (which sounds like the same type of thing).

Pop over and read their discussions on making angel food candy and making sponge candy,then ask questions there. Perhaps they can give you some tips.

Hard Sponge Candy NEW
by: Lori

mine turned out like hard candy. I cooked it to 300°, while calibrating my thermometer first. I never have luck with any candy recipe using a thermometer and I have three different ones that I have tried.

Sponge Candy That Falls NEW

Make sure you use FRESH baking soda when making sponge candy. Some people swear that is the secret to keeping the candy from falling.

Why does sponge candy fall and become so hard...not fluffy NEW
by: mathlesd

My sponge candy falls in the center of the pan. My recipe is:

1 cup sugar
1 cup dark karo syrup
1 TBSP. vinegar
1 TBSP. baking soda (add last)

Cook in a heavy pan to 310 degrees
Add Baking soda, and pour in a buttered 9x9x2 Pan.

I used this recipe for years,but all of a sudden it falls and becomes hard...not fluffy like it always had.

sponge tips NEW
by: Anonymous

You need to use either a small amount of gelatin or vinegar to activate the baking soda to make the candy rise. I cook my sponge to 310 F over medium heat, then add baking soda and whisk quickly.

Fahrenheit or Celsius
by: Angie

Hi Rhonda,

Just another quick clarification... I assumed that you meant 225 and 170 degrees Celsius, but would you confirm that you meant Celsius and not Fahrenheit?

Angle food Candy
by: Rhonda

I found a trick on the internet that worked wonders for me as I have struggled with making this type of candy. After you have poured your mixture in a greased pan, place it in the oven at 225 degrees for 10 minutes and at 170 degrees for another 10 minutes. Candy is puffy and tasty!
