How to Press Edible Flowers
Pressing edible flowers preserves their color and shape for use as decorations on appetizers or desserts. The process relies on heavy, flat pressure to draw moisture out of the petals gradually, leaving behind a thin, dry specimen that retains the essence of the original bloom.
Timing is everything with moisture.
Pick your flowers when they are at their peak and completely dry from dew or rain. If the petals are damp, they will turn brown rather than hold their color.

- Parchment paper
- Unscented facial tissue
- Fine-tipped tweezers
Gradual Moisture Extraction
The goal is to remove internal moisture slowly. If you apply too much pressure too quickly, the petals will tear or turn translucent; use multiple layers of paper to wick the moisture away steadily.
The method.
Prepare the workspace
Lay one of your heavy books open and place a sheet of parchment paper over the pages. Lay a piece of unscented tissue on top of the parchment to act as a primary moisture wick.
Position the flowers
Arrange your clean, dry flowers face down on the tissue. Use your tweezers to straighten individual petals. Ensure no petals are overlapping, as this creates uneven pressure.
Seal the layers
Place a second piece of tissue over the flowers, followed by another sheet of parchment. Carefully close the book.
Apply weight
Stack additional heavy books on top of the one containing the flowers. Move the stack to a cool, dark place where it will not be disturbed.
Wait and check
Leave the flowers for at least one week. Check them by gently lifting the top tissue; if they feel crisp and papery to the touch, they are ready. If they feel cool or pliable, re-seal and wait another few days.
When it doesn't go to plan.
Choose flowers with flat faces, like pansies or violas, which press much more cleanly than thick, bulbous flowers like roses.
Always use unscented tissues to avoid transferring chemical fragrances to your edible ingredients.
If pressing white flowers, check them after 48 hours to ensure they aren't yellowing; if they are, replace the tissue layers to absorb moisture more efficiently.

Can I press flowers in a microwave?
While it is possible to use a microwave to speed up the process, it often compromises the color and causes the petals to become brittle or translucent. Traditional book-pressing is more reliable for long-term storage.
How long do pressed flowers last?
If kept in an airtight container away from direct sunlight, pressed flowers can remain vibrant for up to a year.
