Abstract: Изобретение относится к области пищевой промышленности, в частности кондитерской ее отрасли и касается технологии приготовления мучных изделий. Торт характеризуется тем, что он представляет собой размещенные один над другим слои изделия, нижний из которых выполнен в виде сдобно-сбивного, а верхний – в виде крема. Сдобно-сбивной слой готовят путем предварительного перемешивания со скоростью 240-280 об/мин в течение 20-30 минут маргарина и сахарного песка до получения однородной массы. Затем в смесь добавляют муку пшеничную высшего сорта. Проводят дальнейшее перемешивание смеси с той же скоростью в течение 1-2 минуты. В конце смешивания в нее добавляют сбитую массу, полученную смешиванием разогретого до температуры 70-75°С меда, введенных тонкой струйкой яиц куриных диетических сырых, какао-порошка и смеси соды пищевой с лимонной кислотой. Смешивание сбитой массы проводят до получения ее однородной консистенции. Распределяют полученную массу на кондитерские листы ровным слоем толщиной 5-6 мм. Выпекают полученный пласт при температуре 200-225°С в течение 10-15 минут и охлаждают. Слой из крема готовят путем сбивания со скоростью 280-310 об/мин в течение 10-15 минут, до увеличения объема в 2-3 раза масла сливочного несоленого и молока цельного сгущенного с сахаром с последующим добавлением в массу крема в конце сбивания последовательно ванилина, эссенции ромовой, коньяка и какао-порошка. После чего осуществляют нарезку сдобно-сбивного слоя в виде формы отдельного изделия, размазку на его поверхности крема, с последующей подсушкой изделия и отделку верхней поверхности и боковых поверхностей готового изделия измельченными обжаренными ядрами фундука. Сдобно-сбивной слой и слой из крема соотносятся между собой по массе как (1-1,2 ) : (1-1,2), а измельченные обжаренные ядра фундука берут в количестве 9-9,8 мас.% от общей массы торта. Компоненты сдобно-сбивного слоя берут в следующем соотношении (мас.частях): маргарин – 5-5,5, сахарный песок – 14-14,2, яйца куриные диетические сырые – 7,5-8,5, мед – 4,0-4,2, сода пищевая – 0,7-0,71, лимонная кислота – 0,03-0,032, какао-порошок – 0,5-0,52, мука пшеничная высшего сорта – 37-38,5. Компоненты крема берут в следующем соотношении (мас.частях): масло сливочное несоленое – 13-13,2, молоко цельное сгущенное с сахаром – 26-26,5, ванилин – 0,03-0,032, эссенция ромовая – 0,01-0,012, коньяк – 0,007-0,0071, какао-порошок – 0,05-0,052. При этом обеспечивается улучшение качества торта, создание его с таким составом полуфабрикатов, чтобы исключить перемешивание сдобно-сбивного слоя и слоя крема между собой, благодаря чему обеспечивается увеличение срока хранения изделия до 8 суток. 2 з.п. ф-лы.
