Why is my stevia-sweetened fresh whipped cream bitter? I just used my iSi whipped cream maker for the first time.  I cleaned it thoroughly.  Then, I used a half pint of unpasteurized heavy cream (just bought yesterday with expiration 6 days away), and a few squirts of liquid Stevia.  It came out super bitter.  There doesn't seem to be a ton online about what the cause might be, and the answers I did find were confident but varied.  I've read everything from using bad cream to not enough sweetener or flavoring.  Any thoughts on what the cause might be?
Thank you!
I've been using stevia for years to control my carb intake and  I had to learn by experimenting with it. If you use too much, it will taste bitter. Just add a little at a time, and taste as you go.
