SWEET POTATO STARCH CONTENT RECIPES

Steps:

• Remove the skin carefully and make sure no skin pumps attached, then cut into smaller pieces. Transfer to a blender, add water to cover the sweet potatoes. Blend until really smooth by batches.
• Strain the content to separate residue and the starch liquid. Wash the residue and strain to separate as more starch as possible.
• Set aside until the starch is settled (I recommend at least 4 hours resting).Remove the water gently above. Add around 1L water, mix well, repeat the straining and settling process (make sure no sand and other impurities contained).
• Set the liquid overnight (Note 1) (long resting time helps to remove the water content in the starch block) and pour off the water above. Here we get the pure sweet potatoes starch. Spread on a tray and dry under sun or bake in oven at 50 degree C until well dried.
• If you want to store the sweet potato starch, drying is extremely important. Well dried sweet potato starch can be easily smashed into powder.

Steps:

• Heat the oven to 220C/200C fan/gas 7. Cut off and discard the ends of the potatoes, halve, then cut each half into long wedges.
• Tip the wedges onto a large baking tray. Drizzle over the oil, sprinkle over the thyme or rosemary and plenty of seasoning, then toss to coat.
• Cook in the oven for 15 mins, then turn the wedges over and cook for 15 mins more until golden and tender. Serve.
