Want to make this sauce extra iron-rich? You can also add bone marrow or liver to this sauce and I promise nobody is going to notice. Up to you if you want to add it to the whole batch or just to some of the batch.
Personally I like to grate the liver in (from frozen) as I find its less noticeable in taste and texture. To grate the liver in, simply freeze liver of choice (I like chicken or duck for less flavour, but beef or lamb is fine to use also). I would use around 250g of liver in this meal if adding to the whole sauce. You can grate the frozen liver in on step 5. You can also use a desiccated liver or organ powder!
For a vegetarian option you can also add 1 400g tin of drained cannellini beans or chickpeas at step 5.
