Spicy Spring Salsa

Toss the strawberries and green onion with the white balsamic, sugar, and salt, and let them sit for 30 minutes. Strain off the liquid that comes out into a small pot and simmer it until it has a glaze consistency. Add the glaze to the strawberries and stir in the tarragon and chili flakes. Taste for seasoning and chill until ready to serve.
