I am a pastry chef. I live and work in Johannesburg, South Africa. until now I made cakes and macarons on order from home using 2 domestic ovens both bought in France before I moved to Johannesburg. I bought à convenient & bakery shopl. I am planning to add a Mediterranean deli & French patisseries/viennoiserie/bread sections to my shop. (croissants, brioche, choux eclais cookies macarons cakes etc... Can someone recommend a convection and/or deck oven ? I will need an oven with at least 8 trays for all patisseries including macarons to start with. Ovens I have checked have big fans, not so suitable for macarons and delicat products. I also need a blast freezer going down to -40° which do not seem to exist here? Thank you so much for any help.
