In a measuring cup, stir together the boiling water and hibiscus flowers. Allow this mixture to steep for about 10 minutes, releasing the vibrant color and flavor of the hibiscus.
After steeping, strain the hibiscus tea to remove the flowers. In a blender, combine the strained tea with strawberries and blend until smooth. You should have a thick, vibrant mixture that smells divine.
Next, in a medium pot over medium-high heat, combine the strawberry mixture, sugar, and salt. Bring it to a simmer and cook for 20 minutes. Make sure to skim off any foam that rises to the top during cooking, as this helps achieve a smoother texture.
Once the mixture has thickened, squeeze in the lime juice and transfer it to a jar. Allow it to cool on the counter before storing it in the fridge to chill further.
In a large bowl, whisk together the egg, cream cheese, sugar, and jam until smooth. If you have a stand-up mixer, it makes this process easier, but mixing by hand works just as well!
Transfer the smooth mixture into a piping bag. This will make it easier to fill the pastries without making a mess.
Prepare your workspace by dusting flour on your work surface and rolling pin. Roll out the puff pastry to about an eighth-inch thickness. Cut into squares that are 4 inches by 4 inches.
To create a diamond-shaped danish, take one end of a square and fold it over to meet the opposite end, forming a triangle. Slice two slits in the top of the triangle to create a decorative effect.
Unfold the triangle and fill the center with the cream cheese mixture. Add a small dollop of extra jam on top to enhance the flavor.
Repeat the process until you've used all the puff pastry. Preheat your oven to 375 degrees F and transfer the baking sheet of assembled danishes to the freezer to chill for 15 minutes.
Bake the cheese danishes for about 20 to 30 minutes until golden brown and puffed. Keep an eye on them to ensure they don’t over-bake.
While they’re cooling, whisk together the glaze ingredients until smooth. Drizzle on top of the cooled danishes if desired, and serve with a nice cup of coffee!
