The Perfect Soup Maker

I will hold my hands up and say that I admit to cheating when it comes to soup. Instead of taking over an hour to make soup like most people I use a soup maker, one of the best I’ve ever used as well. I chuck all the ingredients in the soup maker and leave it to do its job. It’s a good soup maker and does everything you could possibly want. I’ve got a Morphy Richards soup maker which doesn’t even cost £50, considering it does a lot of the work I’m happy with that.

I couldn’t recommend getting a soup maker machine enough.

Butternut Squash and Sweet Potato Soup Cost

I’ve always found soup to be delicious and very filling, you just need to make sure that you put the right things into it. This butternut squash and potato soup is amazing and filling, it makes it absolutely perfect for lunches and dinners.

This can be cooked either on the hob and blended down with a hand blender or if you are lucky enough to have one, a soup making machine. I was asked what I wanted for Christmas one year, a soup maker was at the top of that list, so it has allowed me to be super frugal and make some of the tastiest soups ever, I have these for lunches and dinners, especially in the winter when the weather takes a turn for the worst.

If you want to be inventive with soups, you can always see what vegetables you have leftover at the end of the week and see what you can make, you do have to be realistic and see if ingredients would go together, the one for me that also works very well is parsnip curry soup, there is only one word to describe that and that is YUM!

Vegetable Leftovers

Have you ever looked at the amount of peelings that you have leftover when you prepared vegetables for dinner? If you have a rabbit or guanine pig, these it’s easy to get them used up and be waste-free, but if you don’t have a pet that eats your vegetable peelings, is there anything else you can do with it? Well yes, there are two things you can do with them, the first would be to make your own homemade vegetable stock, check out this homemade vegetable stock post. Then once you have made your own stock, you can then put the cooked peelings into the compost to be turned back into goodness for the garden.

I’ve always been a fan of soup, I think it works great for lunches and dinners, soups are generally very simple and easy recipes to make, you just have to consider what will go well together. I do like to get inventive in the kitchen, especially when I’m making soups. I make soups a lot over the wintertime as I find them very warming, filling and just full of the goodness that is needed to make you smile and feel happy. If you like spice, you can consider putting in a bit of chilli or something into the soups to give them a little extra kick.
