Looking at the replies on here, you need to know the difference between beetroot and pickled beets. Beetroot can used in the same way as sugar beet, if it is dried and ground into a flour. It makes fantastic pellets and boilies.
If you buy fresh beetroot, put it through a juicer, keep the juice for later. place the pulp in the oven at 180c for 15-18 minutes. switch of the oven and leave the pulp for a further hour. Place it in a coffee mill and grind it into flour. Use the beetroot flour along with corn flour, icing sugar and the beetroot juice to make pellets. Just as good as betaine pellets at a fraction of the price. ( don't use pickled beetroot, you will need fresh with the skins ) You can also use the beetroot flour in making boilies.
Chopped squares of beetroot left in icing sugar over night, are a super hair rig bait.
Also try strawberries, raspberries and cherry tomatoes. All exceptional when hair rigged on venues that don't allow boilies.
