Combine strawberries, blueberries, raspberries, and blackberries in a large glass bowl. Pour honey and lemon juice over the berries, stirring gently to coat everything evenly. I do this with a rubber spatula rather than a spoon because it's less likely to crush the delicate raspberries and blackberries as you fold things together.

Let the berries sit for exactly eight minutes without stirring. This maceration time allows them to release their juice and infuse with the honey and lemon—if you skip this or rush it, you miss the whole point and the salad tastes like separate components instead of one intentional dish. I've learned this the hard way by trying to speed through this step when I was running late for dinner parties.

Add the sliced kiwi and diced mango to the bowl, folding gently to combine. Why these go in after the berries sit: they're softer and break down faster, so they'll stay more intact if they've only had a few minutes of contact with the acidic lemon juice and honey. Fold with restraint—you're not trying to create a puree, just distribute the fruits evenly.

Stir in the orange segments gently, keeping them mostly whole to avoid releasing too much additional juice. The orange adds a second wave of citrus brightness that makes the entire salad taste more complex than it actually is. Each segment becomes a little flavor bomb rather than just another wet layer at the bottom.

Add the fresh mint leaves just moments before serving, tearing them by hand rather than cutting with a knife. Fresh mint oxidizes quickly when cut, which dulls the herbal flavor you're specifically after in this stunning summer berry fruit salad recipe. I learned this from a frustrated attempt at prepping this salad the morning of a dinner party—the mint was brown by evening.

Taste a spoonful and add another squeeze of lemon juice if needed, depending on how sweet your berries were. Some farmers' market strawberries are nearly syrup-level sweet, while others need coaxing—trust your palate here, not a recipe that can't taste your specific fruit.
