The optical recording of the object wave formed by the resulting interference pattern of two mutually coherent component light beams. In the holographic process, a coherent beam first is split into two component beams, one of which irradiates the object, the second of which irradiates a recording medium.
Make sure to preheat the oven to the correct temperature (220Â°C / 200Â°C fan oven / gas mark 6) before putting your scones in. The 15 minute guideline starts from the point at which you put your scones in a preheated oven. It may also take a bit longer to bake them through in a standard (non-fan) or gas oven. You will also need to extend the time if youâre baking more than 12 tea-time or 24 canapÃ© scones in the oven at the same time.
How to freeze a big batch of homemade waffles. 1  First, cool the waffles on wire racks as soon as they come off the griddle. 2  Line a baking sheet with a sheet of parchment paper and place it in your freezer. 3  Place a layer of (completely cooled) waffles on the baking sheet, leaving a little space in between each. Cover with another sheet of parchment and place a second layer of waffles. If you still have more waffles to freeze, prepare a second baking sheet. Waffles are delicate and you wouldnât want to squish them.
