In the series 'Apple Corer Fun' herewith a second alternative approach using this tool: these Filled Cucumber Rounds are an original side dish or a healthy birthday treat. Really easy to prepare, also by children. In an earlier Instructable an apple corer was used to prepare Watermelon Sticks (CC BY Openproducts, 28 August 2013).

Best results are obtained when applying two apple corers of slightly different diameters: when using only a single apple corer the inner cylinders fit too loosely into the outer rings. The widest apple corer should be used for the filling (the resulting cylinder diameter will correspond to the inside measure of the apple corer), the narrowest should be used for the outer rounds (the hole diameter will correspond to the outside measure of the apple corer). Doing so the tight tolerance will result in a firm snack.

In this example a cucumber was filled with goat cheese, but alternative combinations will work out fine as well. In Step 1 cucumber is filled with watermelon.

In any case, make sure to use all cut-off food in a different dish, for example in a salad. Apropos food waste: in the city of Rotterdam an excellent initiative has been launched to ban food spoiling: Kromkommer (website in Dutch only, freely translated as 'curvedcumber'). This company uses rejected grocery (based on their looks: too much bent, too big or too small but otherwise in perfect condition) for commercializing into their soups.

Step 1 in this Instructable suggests a vegan alternative of the Filled Cucumber Rounds, Step 2 dives into the 'Making Of' this Instructable and finally Step 3 explains the CC BY license of this Instructable.

Step 1: Vegan Cucumber Rounds

The picture above shows a vegan side dish: cucumber filled with watermelon. Many other combinations are possible, I bet that carrot slices make perfect rounds as well... Feel free to post the combinations you made yourself!

The next step shows the 'Making Of' this Instructable.

Step 2: The Making of This Instructable

The organic cucumber was produced locally and in the summer season (avoiding fossil fuel use in greenhouses or extra food mileage). The organic goat cheese was produced in a small local goat farm. The wooden plank was purchased in a local woodworking workshop. The provenance of the organic watermelon is not known. The second apple corer was borrowed.

In the pictures it can be seen that the cucumber/cheese rounds were made with a single apple corer (thus a loose fit). The cucumber/watermelon rounds were made with two slightly different apple corers, resulting in a perfect fit.

To make a simple time-lapse film a number of pictures were bundled in Graphics Interchange Format (GIF). Although animated gifs are not today's standard they have two advantages: firstly they may show as a movie in the introduction picture at the Instructable's overview pages (and other media like www.twitter.com/openproducts and www.pinterest.com/openproducts) and secondly they don't require plugins. An important disadvantage lies in the few colors that are possible (256) and the fact that the file size is relatively large. The animated gifs in this Instructable were created using the GNU Image Manipulation Program (GIMP, open source software, www.gimp.org, version 2.8.10) based on a series of photographs:

'File' > 'Open as Layers' > [select all pictures];
'File' > 'Export As' > [filename.gif] > tick 'As animation'.
