What should it look and smell like?

OGGS® Aquafaba is a brown, cloudy liquid, with a sweet and slight beany aroma. Once you start whisking it however, it gets much paler and will produce a white foam. The longer you whisk for, the thicker the mixture will be. To create soft peaks that leave a slight trail, we recommend whisking for 2-3 minutes. For completely stiff peaks, you should whisk for 4 minutes on a high speed. The Aquafaba has a sweet and slightly beany smell.
