Analysis

Core components:

  • Grilled cheese: Bread, cheese, fat for cooking
  • Tomato soup: Tomatoes, aromatics, liquid base, enriching elements

Key processes:

  • Maillard reaction for bread browning
  • Fat emulsion for soup richness
  • Cheese protein melting transitions
  • Acid-fat balance in soup

Critical control points:

  • Bread toasting temperature
  • Cheese melting point
  • Soup emulsion stability

Batch cooking considerations:

  • Soup excellent for batch preparation
  • Grilled cheese best made fresh
  • Storage impact on soup emulsion

Overview

  4. Add canned tomatoes with their juice, stock, thyme, and honey. Bring to simmer.
  5. Reduce heat to medium-low, simmer uncovered 30-40 minutes.
  6. Add cream and basil. Using immersion blender, blend until smooth.
  7. Season with salt and pepper to taste.

Grilled Cheese

  1. Mix grated cheeses together.
  2. Butter one side of each bread slice generously.
  3. Heat non-stick skillet over medium-low heat.
  4. Place bread butter-side down in skillet.
  5. Add cheese mixture (about 4 oz total per sandwich).

Science Notes

Soup Science

  • San Marzano tomatoes provide ideal balance of sweetness and acidity
  • Honey helps neutralize tomato acidity
  • Fat from cream and butter creates stable emulsion
  • Blending while hot promotes emulsion stability

Grilled Cheese Science

  • Room temperature butter ensures even spreading and browning
  • Medium-low heat allows proper cheese melting while achieving optimal Maillard reaction on bread
  • Mixture of aged cheddar and Gruyère provides optimal melt properties and flavor complexity
  • Covering briefly creates steam environment for proper cheese melting

Storage Guidelines

Soup Storage

  • Cool completely before refrigerating
  • Store in airtight containers
  • Keeps 4-5 days refrigerated
  • Can be frozen up to 3 months
  • When reheating, warm gently while stirring to maintain emulsion

Grilled Cheese

  • Best prepared fresh
  • Do not store assembled sandwiches
  • Cheese can be grated and mixed ahead, stored up to 5 days

Batch Cooking Notes

Soup Scaling

  • Recipe easily doubles
  • Maintain simmer time regardless of batch size
  • Cool in smaller containers for faster chilling

Components to Prep Ahead

  • Grate and mix cheeses
  • Chop onions and garlic
  • Make full batch of soup

Fresh Components

  • Always cook grilled cheese to order
  • Fresh basil garnish for soup

Troubleshooting

Soup Issues

  • If soup breaks (separates), re-blend while hot
  • If too thick, thin with warm stock
  • If too acidic, add more honey or cream

Grilled Cheese Issues

  • If bread browns too quickly, lower heat
  • If cheese isn’t melting, cover pan briefly
  • If bread is too dry, add more butter
