Iām dying to get access to the coveted recipe! I have lots of problems with browning and hollows. This batch didnāt brown because I propped open our Arianna convection 133 oven door for a part of the bake time. In the end, all LOOKED great on the outside, but some over cooked and were hollow, some were undercooked and hollow. Iām hundreds of batches in and just cannot figure out how to use my new convection oven! Over the past two weeks, Iāve had two 13 gallon trash bags full of failures. Iām beyond frustrated. Iāve raised and lowered the temp, adjusted cook times, vented for various amounts of time, oven dried, showers, covered racks with foil to deflect heat, went back to using a pan with sides, even propped a pan at the front of the oven in attempt to block the heat from hitting the cookies directly. Made Italian method for 1st six months, then moved to Swiss method so I could try Sugar Beans recipe and cook times (she has the same convection oven I have. I prefer the look of Italian but Iāll do anything to make this work. I have special orders coming out my ears over the next month! Had never planned to start a macaron business, but my husband was laid off for 5.5 months and we had to do something. So unfortunately we are still in R&D phase and have orders rolling inā¦.. The swirl batch in the picture were a failure, and the chocolate was the only successful batch Iāve had in weeks. Any advice or encouragement would be much appreciated! Thank you!!
