Your meringue won't thicken likely due to residual fat in the mixing bowl or on utensils, or undissolved sugar. Ensure all equipment is spotlessly clean and free of grease. Also, make sure to add sugar slowly to the egg whites while beating, ensuring each addition is completely dissolved before adding more. Using fresh eggs at room temperature can also help achieve better results.
