In a small bowl combine crème fraiche and 2 teaspoons lemon juice and stir to combine. Season to taste.
Fill a large saucepan until 8cm deep with cold water. Bring to the boil over medium heat. Reduce heat to a simmer and crack 1 egg into water and cook for 3 minutes. Remove with a slotted spoon. Drain on paper towel. Keep warm while you cook the remaining eggs.
To assemble, place two muffins each on four serving plates, arrange spinach and Huon Premium Smoked Salmon. Top with a poached egg, then a drizzle of crème fraiche mix, top with chives if desired and serve at once.
