For a number of years The Parson and The Publican have travelled the highways and byways in search of refreshment for body and soul. With many years between them of accumulated wisdom on matters pertaining to pew and pump it was but a short step to committing their experiences to print. The authors have scoured Worcestershire, Herefordshire and The Wye Valley to amass these tales, which are delightfully illustrated with watercolour sketches from the brush of the Publican. Some of the places in their delightful book are well known, while others are more obscure but, never discouraged, our plucky pilgrims get out the map, freely exchange opinions and then do precisely what the driver wishes. Not for them the wonders of the 'Sat Nag'. Rather, instinct and an unwavering nose for musty hassocks, malted barley or fermented apple juice draws them ever onwards.

Nozedar’s recipes and remedies are exquisitely illustrated in watercolours by Lizzie Harper. She talks while Harper illustrates live.
