During a trip I tasted a lovely breakfast bowl with a base of açaí purée, topped with granola and fresh fruit. And I thought: I can make that. One key component was that the purée was very cold, almost frozen, and that was a big part of why it was delicious on a hot summer morning.
I had fresh banana and frozen raspberries, so I blended them with a bit of water. I added some granola (a simple version, made with oats, sunflower seeds, almond flakes and agave), then I topped it off with a fresh nectarine.
The second time I made it, I used frozen banana and peach juice, and topped it with blueberries. It was less visually striking but the taste was even better.
The third time I used frozen bananas, water, and fresh blueberries and topped it with melons.
The best results were with frozen banana and fruit juice. Adding water dilutes the fruit purée too much.
