Cook techniques
Slow Cooking
Slow cooking involves cooking food at low temperatures for an extended period, allowing flavors to meld and develop. In this recipe, a slow cooker is used to combine crushed tomatoes, diced tomatoes, onion, garlic, basil, salt, pepper, and broth. Cooking on high for 2 hours or low for 4-8 hours ensures the vegetables become tender and the flavors intensify.
Blending
Blending is a technique commonly used to create a smooth texture in soups and sauces. After slow cooking the ingredients, the mixture is transferred to a blender or food processor to puree until smooth, providing a creamy consistency to the soup.
Making a Roux
A roux is a mixture of fat (butter) and flour used to thicken sauces and soups. To prepare the roux for this recipe, butter is melted in a saucepan, and flour is added and stirred until clumpy, followed by whisking in heavy cream or half and half until thickened and smooth.
Melting Cheese
Melting cheese adds creaminess and flavor to dishes. In this recipe, shredded Parmesan cheese is added to the slow cooker with the prepared roux, allowing it to melt into the soup for a rich, cheesy flavor.
Garnishing
Garnishing enhances the presentation and flavor of a dish. This recipe suggests topping the soup with additional fresh basil and Parmesan cheese before serving to add texture, color, and flavor.
