又到喝汤季节 新手煲汤入门守则
要使喝汤真正起到强身健体、防病治病的作用,在汤的制作和饮用时有一定的科学原则要遵循,否则就可能出现偏差。长时间加热会破坏煲类菜肴中的维生素,而加热1~1.5小时,可获得煲汤比较理想的营养峰值,此时的能耗和营养价值比例较佳。
选料要得当
用于制汤的原料,通常为动物性原料,如鸡肉、鸭肉、猪瘦肉、猪肘子、猪骨、火腿、板鸭及鱼类等。采购时应注意必须鲜味足、异味小、血污少。这类食品含有丰富蛋白质和核苷酸等,家禽肉中能溶解于水的含氮浸出物,是汤鲜味的主要来源。煲汤材料的新鲜并不是指传统的“肉吃鲜杀,鱼吃跳”的时鲜,而是指鱼、畜、禽杀死后3小时~5小时,此时鱼、畜或禽肉的各种酶使蛋白质、脂肪等分解为人体易于吸收的氨基酸、脂肪酸,味道也最好。
炊具要选择
传统煲汤多用陈年瓦罐,其通气性、吸附性好,还具有传热均匀、散热缓慢等特点,但是使用不当便易碎易坏。现代主妇更乐于选择康宁晶彩透明锅,其以透明琥珀色系列的煮锅及单柄锅闻名,是全世界第一个透明锅,由一种不怕冷热温差的玻璃陶瓷材质所铸造。可达5 0 0℃的耐热温差,即使在粗心空烧状态也不会有安全的顾忌;而透明的特性让使用者很容易检视炊具的火候而随时调整,可避免溢出或焦黑。聚热保温材质的特性很适合水煮及煲汤或煎熬中草药,只用中、小火即可获最佳的炖煮效果。
