Stewed strawberries really have a special taste that I just love. Don’t you? But unless you use a lot of sugar, cook long or add apple or banana, strawberry sauce is often too liquid. This is the reason why I suggest adding fresh strawberries at the very last moment.
And, depending on your taste or if you find fresh herbs, I propose to add at the end of the cooking process fresh basil leaves (or mint, that’s also very good). They will gently infuse while the preparation cools down.
Note that the amount of sugar is indicative as it depends on the quality of strawberries. If strawberries are ripe, then no sugar is fine. If it’s the beginning of the season and they are not so sweet, then a bit of sugar might be helpful.
