Blend or mash fresh strawberries into a smooth puree. Strain if desired.
Combine cold milk, strawberry puree, and vanilla in a jar. Shake vigorously 15 seconds until lightly foamy.
Fill a glass with ice. Pour espresso or cold brew over ice.
Spoon strawberry cold foam gently over the top and serve immediately.
Cold foam works because milk proteins trap air bubbles when agitated, creating a stable foam without any heat. Strawberries contain aromatic ester compounds that give them their signature berry scent — those same compounds carry beautifully through dairy fat, which is why strawberries and cream is a pairing that spans almost every cuisine.
