Recently I have found that when I cram in too many different fruit and vegetables to one drink my taste buds get a sensory overload. Keeping things simple allows me to really taste the one, two or at most three different ingredients I am drinking. Adding a wide variety of ingredients to one drink potentially increases the variety of nutrients that you consume.
I find that adding ginger makes juices taste even better. For example:
carrot and ginger becomes carrot, orange and ginger
apple and ginger becomes apple, spinach and ginger
There are many other simple juicer recipes available freely on the internet. One that caught my eye today was a cucumber, tomato cooler!
It's always nice finding recipes and hearing other people's take on what makes a great juice as it gives me new ideas to try out.
