Rinse the split peas until clean. Drain. Pour into the pressure cooker and cook for about 30 minutes. Strain.
2. 倒入炒锅,加入砂糖后中火炒制。当用勺子挑起的豌豆糊成团状而不是液体状跌落时就可以熄火了。
Place a big enough skillet over the medium heat. Pour in the split peas puree and add in sugar. Cook and stir constantly until the mixture has thickened. Switch the heat off.
Cover a rectangle baking pan with a plastic wrapper. Spread the peas puree evenly into the pan. Cover the surface with another plastic wrapper. Brush the surface even and smooth. Chill over night after it completely cooled down. Slice them into the desired patterns.
