Start by boiling a large pot of water, adding kosher salt once it is bubbling vigorously. Toss in the bowtie pasta and let it cook until it is al dente. Keep an eye on it and taste a piece as it approaches the cooking time to ensure it maintains that perfect bite and is not mushy.
Remove the kernels from the fresh corn ears, allowing them to tumble onto a cutting board. Grill them lightly until bright and slightly sweet, keeping the char to a minimum to retain that fresh taste. Avoid burnt bits as they can ruin the flavor.
In a mini food processor, blend fresh basil leaves, garlic cloves, red wine vinegar, and water. Drizzle in the olive oil as you pulse the mixture. Aim for a bright green color and a smooth texture, but do not over-process as this may cause the dressing to turn brown.
In a large bowl, toss the cooled pasta with your grilled corn and halved cherry tomatoes. Then, drizzle the basil dressing over everything. Ensure all ingredients are well coated; otherwise, flavor may not shine through. Be light-handed to keep the salad refreshing.
Sprinkle in the grated parmesan and add a touch more kosher salt to taste. Gently stir to maintain the salad's beautiful appearance and prevent clumping. Taste as you go to avoid overpowering it with too much salt.
Let the salad chill in the fridge for about 30 minutes to allow the flavors to mingle. Enjoy it fresh and zesty, but take care to not let it sit for too long to avoid sogginess.
