I haven't heard of beans being grinded with mortal like this and I guess the taste would be different. I might try something like this to see how it tastes too. Though I use the local grinding stone for mine as I don't have a blender. I love bean cake so much and enjoy making it myself at home.
Thanks for sharing 👍
Thank you too @princessbusayo. Making bean cake using Mortar pestle method is the same with the grinding stone method because its traditional and will taste the same. You can try making bean cake with the mortar method and see how it taste. Thank you @princessbusayo for stopping by. Blessings
