How to Make It
Fill a medium bowl with ice water. In a medium saucepan of salted boiling water, blanch the fava beans for 2 minutes. Drain and transfer to the ice bath to cool completely. Slip off and discard the skins.
In a large skillet, heat 2 tablespoons of the oil. Add the corn and fava beans and cook over moderately high heat, stirring occasionally, just until the corn is crisp-tender, about 3 minutes. Season with salt and pepper. Transfer to a plate and let cool to room temperature.
In a large bowl, whisk the vinegar with the remaining 2 tablespoons of oil. Add the arugula, tomatoes, mint, basil and the corn mixture and season with salt and pepper. Toss to coat, then spoon onto plates. Scoop the burrata into pieces and gently spoon it onto the plates. Season with pepper and serve.
