Step 1: Prepare the Candied Almonds. In a small heavy skillet, heat sugar over medium-low flame, stirring gently for about 10 minutes until it melts and turns a rich caramel color. Once melted, quickly stir in the slivered almonds to coat them evenly. Pour the mixture onto a sheet of foil, spreading it out to cool completely before breaking it into pieces.

Step 2: Mix the Salad Greens. In a large bowl, combine the crisp romaine lettuce, sliced red onion, and vibrant fresh strawberries. Toss these ingredients gently.

Step 3: Whisk Together the Dressing. In a small bowl, whisk together mayonnaise, sour cream, and milk until smooth. Then stir in apple cider vinegar, sugar, and poppy seeds.

Step 4: Combine Salad and Dressing. Drizzle the dressing over the salad ingredients and gently toss until coated.

Step 5: Add the Candied Almonds. Just before serving, break the cooled candied almonds into smaller pieces and sprinkle them over the salad.
