双色地瓜土司 Duo Tone Sweet Potato Loaf


Last week I posted the recipe on potato buns which received a lot of positive feedback hence this week I decided to continue with using potatoes for creating a two tone bread. Potatoes, sweet potatoes and pumpkins are nearly almost available in my household. 
上周我在博客发布的马鈴薯面包得到许多好评,所以这个星期还是以薯类来制造面包。由于家里随时都有购买到各种地瓜,马鈴薯和金瓜,便决定来个双色地瓜面包土司吧!

My oldest pooch, Coco was born with hereditary allergies at birth, a condition we suspected to come from the rampant breeding from puppy mills. We bought her from the neighborhood pet shop and we were painted a beautiful picture of the puppy's origin when the pet shop owner insisted that the puppy with AKA certification are all good to go. Since the day Coco came into the household she has had a year of numerous incidents of uncontrollable fits, severe skin conditions, chronic ear infections and we practically tried all methods to relief her suffering.
我的大女犬可可天生就多病痛,即始是从宠物商店购买回来再加上狗狗还附带纯种狗证书,都不能确保狗儿的身体壮态。可可幼小就时常进医院治疗多次发作的病态,非常可怜。

It's only after a year of putting her through countless therapy, immunology treatments, steroids that we decided to call its quits. Her regular vet proposed to conduct a blood test to determine the type of food or external factors that we could avoid and to lessen her contact from.  During that time such test wasn't available in Malaysia so her blood samples had to be sent over to the laboratory in USA. It took almost one month for the laboratory to conclude the test outcome.
经过了一整年的漫长医治及踩用许多的药物来控制,兽医终于提议把可可的血送去美国的专业测试实验室进行检验试看可否找出病因而加以预防或是帮减少爱犬的痛苦。之后还等了一整个月才拿到检验报告。

The report listed a long list of items ranging from sensitivity level, and the most allergic food which we had been continuously feeding her was lamb and rice formula dog food. If you have dogs with sensitive skin conditions, usually, most commercial brands of dog food would normally strongly promote lamb meat against other kinds of meat. Since Coco's problems was so severe that she is allergic to almost anything, e.g. lamb, beef, rice, peas, yeast, cats, dust, dust mites, grass, mangoes, just to name a few. With such conditions, we were forced to prepare home cooked meals for her until today. Potatoes and pumpkins are her constant carbs to replace flour, rice and peas. 
结果才明白原来那一整年里不断地购买不同品牌的羊肉,米,面粉之类的狗粮都是它极之过敏的食品。特别是大多数商业品牌的狗粮通常会强烈推擴羊肉类似的狗粮来刻服皮肤敏感问题。处此以外,可可对于一切米粮,酵母,碗豆,猫,灰尘,许多种草类,芒果等都非常过敏。自从那时开始我就亲自下厨特别准备给予爱犬吃。

Anyway, such is why I have ample supply of potatoes and pumpkins at home at all times.  
就以以上原因何为家里随时都存有不同的地瓜及薯类的蔬菜。
