          Analyze this screenshot of a recipe webpage and extract recipe information.

          - Extract all available information visible in the screenshot.
          - If something is not found, use null for optional fields.
          - For ingredients, parse quantities and units.
            - Always provide heuristicAmount + heuristicUnit when possible, and also provide measuredAmount + measuredUnit when possible.
              - (e.g., "2 cups flour" -> measuredAmount: 250, measuredUnit: 'g', heuristicAmount: 2, heuristicUnit: 'cups', name: "flour")
            - Do use the same values for heuristicAmount and measuredAmount.
            - In most cases a recipe will have heuristicAmount and we should guess a measuredAmount
          - If the ingredient name contains some preparation (i.e melted, beaten, etc.), remove it from the name and add it to the notes. (e.g., "2 cups melted butter" -> measuredAmount: 250, measuredUnit: 'g', notes: "melted", name: "butter")
          - For "group": If ingredients are organized into groups (e.g., "For the sauce:", "For the pasta:", "For the marinade:"), include the group name in the "group" field. If ingredients are not grouped, set it to null.
          - Represent tablespoon as tbsp and teaspoon as tsp.
          - Convert all times to minutes and output numbers (not strings) for numeric fields.
          - Generate a description if one is not provided.
          - For "source": Try to identify the source name. Use null if unknown.
          - For "url": Always include the source URL (${url}) here.
